Answer:
610 m^2
Step-by-step explanation:
Area of the shaded region = area of the outer rectangle - area of the inner rectangle
Area of the outer rectangle
l = 42
b = 25
a = l*b = 42*25 = 1050m^2
Area of the inner rectangle
l = 22
b = 20
a = l*b = 22*20 = 440m^2
Therefore, the area of the shaded region is = 1050 - 440
= 610m^2

Look at this net for a rectangular prism.
What is the surface area of the solid created by the net? Show your work.
the second part of the question EXPLAIN YOUR THINKING PLZ HELP
The length of the rectangular face is 15 cm, and there are 4 rectangular faces in the rectangular prism. If the length of the rectangular faces in the prism was tripled to 45 cm, what would happen to the size of the 2 rectangular bases of the prism? Explain your thinking.
Answer:
Step-by-step explanation:
the surface area = area of the 4 faces+ area of the 2 bases
4 *(15*8) + 2*( 8*6) = 480+96 = 576 cm²
if the length of the faces tripled, the two bases remain unchanged because the prism just gets taller on the same bases.

A rectangular yard has area 96 square feet. The width of the yard is 4 feet less than the length. Find the length. in feet, of the rectangular yard.
Answer:
24 ft
Step-by-step explanation:
To find the missing length, we start with the area. We know that we have an area of 96 square ft (although i dont know why someone would have such a big yard). We also know that the width of the yard is 4 ft. The next thing we do is divide. Since we multiply the length and width to find the area, we will divide the area by the width to find the missing length. 96/4= 24. Btw here is the weird yard someone has lol ( i made it to the best of my ability)
|----------------------------------------------------------|

Answer:
length=12 feet
Step-by-step explanation:
l*w=a
l*w=96
factors of 96: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96
12*8=96
12-8=4

Answer: 74 inches
Step-by-step explanation:
Since we are given the equation of the regression line for the son's height y to be:
y = 0.5x + 38
where,
x = father's height = 72 inches
Then, we put the value of x into the equation and this will be:
y = 0.5x + 38
y = 0.5(72) + 38
y = 36 + 38
y = 74 inches
Therefore, the son is 74 inches.

Molly roller blades at a constant speed, travelling 8 km from her home to the library in 0.5 h. What was the rate of change of distance with respect to time?
Answer:
speed = Distance ÷ time
Step-by-step explanation:
S = 8km ÷ 0.5h
S = 16km/h
The rate of change of distance with respect to time was 16km/hr.
What is the average speed?Calculating average speed involves dividing the total distance traveled by the total time it took to cover that distance. Speed is the rate of movement of something at a specific time. Average speed refers to the average speed over the course of a journey.
How to solve this problem?Here, the total distance = 8km
Total time = 0.5 hr
Then the rate of change = total distance/total time = 8/0.5 = 16km/hr
Therefore, the rate of change of distance with respect to time was 16km/hr.

Consider the equation 5 – 3(2x – 7) = 12 – 5(x – 2). Is x = 2 a solution to this
equation? Is x = 4 a solution to this equation? Explain your reasoning in each case
Answer:
see below
Step-by-step explanation:
5 – 3(2x – 7) = 12 – 5(x – 2)
Substitute x=2
5 – 3(2*2 – 7) = 12 – 5(2 – 2)
5 – 3(-3) = 12 – 5(0)
5 - 3*(-3) = 12
5+9 = 12
14=12
This is false so it is not a solution
5 – 3(2x – 7) = 12 – 5(x – 2)
Substitute x=5
5 – 3(2*4 – 7) = 12 – 5(4 – 2)
5 – 3(8-7) = 12 – 5(2)
5 - 3*1 = 12-10
5-3 = 2
2=2
This is true so it is a solution

b. (-1, 4)
c. -3, 1
d. x = -1
Step-by-step explanation:
a. There is a maximum value of the function (highest point) because the parabola opens downward.
b. The vertex is the turning point--the point where the maximum is.
c. The roots (or "zeros") are the values of x where the curve intersects the x-axis
d. The axis of symmetry is a vertical line which passes through the vertex.

The radius of the circle whose equation is x² + y² + 8x - 6y + 21 = 0 is 2 units
Radius of a circleSince the equation of the circle is x² + y² + 8x - 6y + 21 = 0, to find the radius, we complete the square in the terms x and y and convert it to the form (x - a)² + (y - b)² = r² (1) which is the standard equation of a circle.
So, x² + y² + 8x - 6y + 21 = 0
x² + 8x + y² - 6y + 21 = 0
x² + 8x + (8/2)² - (8/2)² + y² - 6y + (-6/2)² + (-6/2)² + 21 = 0
x² + 8x + 4² - 4² + y² - 6y + (-3)² - (-3)² + 21 = 0
(x + 4)² - 4² + (y - 3)² - (-3)² + 21 = 0
(x + 4)² - 16 + (y - 3)² - 9 + 21 = 0
(x + 4)² + (y - 3)² - 16 - 9 + 21 = 0
(x + 4)² + (y - 3)² - 4 = 0
(x + 4)² + (y - 3)² = 4 (2)
Comapring (1) and (2), r² = 4
So, r = √4
r = 2
So, the radius of the circle whose equation is x² + y² + 8x - 6y + 21 = 0 is 2 units

The radius of the circle given by the equation is 2.
What is Circle?Circle is a two dimensional figure which consist of set of all the points which are at equal distance from a point which is fixed called the center of the circle.
Standard form of a circle is given by the equation,
(x - h)² + (y - k)² = r²
where, (h, k) is the center of the circle and r is the radius of the circle.
Given equation is,
x² + y² + 8x - 6y + 21 = 0
(x² + 8x + 16) + (y² - 6y + 9) - 4 = 0
(x + 4)² + (y - 3)² = 4
(x + 4)² + (y - 3)² = 2²

Answer:96.267
Step-by-step explanation:
There are 1,444 paperweights and one box will hold 15 paperweights
So you will divide 1,444 by 15, which would give you 96.267
So you would need 96 boxes and an extra box, which won't be full holding 4 paper weights

2x + 2y = 12
6x - 2y = 20
Answer:
The solution, as an ordered pair, is (4, 2).
Step-by-step explanation:
2x + 2y = 12
6x - 2y = 20 Adding the 2 equations will eliminate y:
8x + 2y + (-2y) = 32
8x = 32
x = 4.
Substitute x = 4 in the first equation:
2(4) + 2y = 12
2y = 12 - 8
2y = 4
y = 2.
