Answer:
zero, because the discriminant is negative
Step-by-step explanation:
By writing the quadratic formula, we have the discriminant written in the root as;
b^2-4ac
Now, given the expression, we can see that the discriminant here is -19
What this mean is that we have a negative discriminant
Hence, we can conclude that the roots are complex and as such, none of the roots are real

What is the area of this rectangle? A rectangle that is partitioned into two rectangles. The first rectangle has a measurement of five meters along the top, and a measurement of eight meters along the side. The second rectangle has a measurement of five meters along the top, and a measurment of eight meters along the side. 50 square meters 60 square meters 70 square meters 80 square meters
Answers
Answer:
80 square meters
Step-by-step explanation:
A rectangle that is partitioned into two rectangles; rectangle A and rectangle B
Rectangle A:
Top = 5 meters
Side = 8 meters
Area of rectangle A = length × width
= 5 meters × 8 meters
= 40 meters ²
Rectangle B:
Top = 5 meters
Side = 8 meters
Area of rectangle B = length × width
= 5 meters × 8 meters
= 40 meters ²
Total area of the partitioned rectangle = area of rectangle A + area of rectangle B
= 40 meters ² + 40 meters ²
= 80 meters ²
Decide whether QRST and you UVWX are similar.
Answers
Answer:
no
Step-by-step explanation:
Answer:
They are not similar.
Step-by-step explanation:
Let's compare 2 sides of QRST and the 2 corresponding sides in UVWX, and set up a side length ratio.
20/19 = 15/7. If these ratios are equal the shapes are similar, but the ratios obviously aren't.
Sooo....the shapes aren't similar.

You are framing a picture with a frame of equal width on each side.
a. Write a polynomial that represents the area of the picture including the frame
b. Find the area of the picture including the frame when the width of the frame is 2 inches
Answers
Answer:
Part A)
The polynomial is:
[tex]A=4(x+8)(x+10)[/tex]
Or, expanded:
[tex]A=4x^2+72x+320[/tex]
Part B)
When the width of the frame is two inches, the area of the picture including the frame is 480 square inches.
Step-by-step explanation:
Part A)
For solely the picture, the width is 16 inches, and the length is 20 inches.
If we include the width of the frame, then we will have to add x to both sides of the 16 inches. Then the new width will be (16 + 2x) inches.
Likewise, the new length will be (20 + 2x) inches.
The area of a rectangle is given by its width multiplied by its length. Then the polynomial that represents the area will be:
[tex]A=(16+2x)(20+2x)[/tex]
To simplify calculations, we can factor out a two from both factors. Thus:
[tex]A=2(8+x)\cdot 2(10+x)=4(x+8)(x+10)[/tex]
Expanded, this will be:
[tex]A=4(x^2+18x+80)=4x^2+72x+320[/tex]
Part B)
When the width of the frame is two, x = 2. Then the area is:
[tex]A=4(2+8)(2+10)=4(10)(12)=40(12)=480\text{ inches}^2[/tex]
The area of the picture including the frame will be 480 square inches.

24f2+11
Answers
Answer:
24t^2 + 11
Step-by-step explanation:
There is a lot left out of this question. If you are allowed rational numbers, a common factor could be 24.
24(t^2 + 11/24) is one possibility.
I think what you mean is there an integer that is a common factor. There is not.
So the answer is 24t^2 + 11
There is one more thing that needs to be clarified. Can you give t a value? If you can, then t = 11
the common factor would be
11(24 * 11 + 1)
I doubt very much that this is what is meant, but the question really should make it clear.
Answer:

Step-by-step explanation:

Issac shovels driveways to earn money. He can shovel 14 driveways in 8 hours. Earns $25.00 for each driveway. Issac is saving up to buy a new computer that costs $831.25. How many hours does Issac need to work to earn enough money to purchase the computer?
Answers
Answer:
19 hours
Step-by-step explanation:
Issac shovels driveways to earn money. He can shovel 14 driveways in 8 hours. Earns $25.00 for each driveway. Issac is saving up to buy a new computer that costs $831.25. How many hours does Issac need to work to earn enough money to purchase the computer?
Step 1 find the number of driveways to shovel
25x = $831.25
x = $831.25/25
= 33.25 driveways
Step 2
He can shovel
14 driveways = 8 hours
33.25 driveways = x
Cross Multiply
14x = 8 × 33.25
x = 8 × 33.25/14
x = 19 hours
Write the equation of each circle. center at (-4, 3), radius 9
Answers
Answer:
(x-h)²+(y-k)²=r²
putting respective value
(x--4)²+(y-3)²=9²
(x+4)²+(y-3)²=81
Answer:
(x + 4)^2 + (y - 3)^2 = 9^2
Step-by-step explanation:
Here our center is at (-4, 3), so h = -4 and k = 3. Radius, r, is 9.
Insert these values into the standard equation of a circle centered at (h, k) with radius r:
(x - h)^2 + (y - k)^2 = r^2 becomes:
(x + 4)^2 + (y - 3)^2 = 9^2

Question 9 (1 point)
In the middle school PTA there is a total of 47 men and women. The number of women the PTA is 2 more than four times the number of men. How many women are in the
PTA?
Let the number of men = x
Let the number of women = y
x + y = 47
y = 2 + 4x
We substitute
x + 2 + 4x = 47
Collect like terms
5x = 47 - 2
5x = 45
x = 45/5 = 9
y = 2 + 4x
y = 2 + 4 × 9
y = 2 + 36
y = 38
Therefore, the number of women = y = 38 women
