Step-by-step explanation:
width= x (let)
length= x+5
Area=50 cm
Now ,
area = l ×b
50 = (X×X+5)
50 = (2X + 5)
50÷ 2= X+5
25 -5 = X
X=20
LENGTH = X+5
20+5

If f(x) = 3x² -1 and g(x) = x+2, find (f + g)(x).
Answer:
(f+g)(x) = 3x^2+x+1
Step-by-step explanation:
It may look hard at first, but all the question is asking you to do is add both of the equations together.
(f+g)(x) = (3x^2-1) + (x+2)
(f+g)(x) = 3x^2+x+1

A rectangular piece of material with sides 150 cm and 100 cm is used to make a circular table cloth. the diameter of the completed cloth must be 0.9 m and 5 cm is provided for the hem. how much material is wasted?
The material wasted is 7915.375 sq cm.
What is area of rectangle?The product of its length and breadth.
Area = length* breadth
Given:
length= 150 ac, breadth = 100 cm
d= 0.9m 5cm

In one country, approximately 144,000 of 900,00 residences are rentals. Determine the percentage of residences in the country that are rentals
The 62.5% of residences in the country that are rentals if the total number of residence in the country is 144,000.
What is the percentage?It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.
We are assuming:
Total number of residence in the country = 144,000
In which 900,00 residences are rentals.
Percentage of residences in the country that are rentals:
= (90000/144000)×100
= 0.625×100
= 62.5%
Thus, the 62.5% of residences in the country that are rentals if the total number of residence in the country is 144,000.

To solve this system of equations using substitution, what could be substituted in place of y in the first equation?
4x=5-2y
y-2x=7
Answer: y=2x+7
(this is a rearranged version of y-2x=7 from question)
Step-by-step explanation:
4x=5-2y
y-2x=7
i would rearrange the 2nd value into y intercept form y=mx+b
so move the -2x to the other side of the = sign by doing the opposite, +2x on both sides to isolate the y

The angle marked a=92 degrees.
work out the angle marked x.
Answer:
x is 92 degrees
The lines x and a are parallel and congruent, meaning they are evenly proportioned and have the same length.
Point A in this figure is to be rotated 90° in a clockwise direction. The center of the rotation is the origin. A (0,5) C (6,3) B (2,-2) Where does point A end up?
Answer:
B
Step-by-step explanation:
To rotate triangle ABC about the origin 90° clockwise we would follow the rule (x,y) → (y,-x), where the y-value of the original point becomes the new x-value and the x-value of the original point becomes the new y-value with the opposite sign.

The probability of drawing three queens from a standard deck of cards is 0.000162.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
P(E) = Number of favorable outcomes / total number of outcomes
Total cards = 54
No. queens in a deck = 4
Probability of drawing a queen card = 4/54
Now that 1 queen has been taken, the no. of cards becomes = 53
and
no. of queens = 3
Probability of getting a queen again = (3/53)(4/54)
Two queens have already been removed.
No. of cards in the deck = 52
No. of queens in the deck = 2
Probability of drawing three queens
= (2/52)(3/53)(4/54)
= 0.000162 approximately

The approximate solution to the given equation is x ≅ 148.4. The correct option is C. x ≈ 148.4
Solving equationsFrom the question, we are to determine the approximate solution to the given equation,
The given equation is
[tex]4lnx -8 =12[/tex]
First, add 8 to both sides
[tex]4lnx -8+8 =12+8[/tex]
[tex]4lnx =20[/tex]
