Answer:
1. A. 12a^2 + 8a + 4
2. C. 4xy+16x-4y^2-16y
3. C. 64q^6r^8s^4
4. A. -4x^4y^6
Step-by-step explanation:
48a^3 + 32a^2 + 16a / 4a = (48a^3) / 4a + (32a^2) / 4a + (16a) / 4a = 12a^2 + 8a + 4.
So, the answer is A. 12a^2 + 8a + 4.
(2x-2y)(2y+8) = 4xy - 4y^2 + 16x - 16y.
So, the answer is C. 4xy+16x-4y^2-16y.
(-8q^3 * r^4 * s^2)^2 = (-8)^2 * q^6 * r^8 * s^4 = 64q^6r^8s^4.
So, the answer is C. 64q^6r^8s^4.
-12x^8y^8 / 3x^4y^2 = (-12 / 3) * (x^(8 - 4)) * (y^(8 - 2)) = -4x^4y^6.
So, the answer is A. -4x^4y^6.
Hope this helps!
Answer:
QR = 3
Step-by-step explanation:
given that Q is on the segment PR , then
PQ + QR = PR ( substitute values )
16 + QR = 19 ( subtract 16 from both sides )
QR = 3
There is no Venn diagram so how do we solve it. There is nothing to help us with this answer so right now there is no definite amount.
Remark
You can just look at the graph to find out the y intercept. The y intercept is the point where x = 0. The point for the y intercept is (0,-2). So B is definitely wrong.
To get the slope, you can just use the x intercept which is (-3,0)
When y = 0, x = - 3. We need to do a little calculation to get the slope.
So far what we have is
y = mx - 2
y = 0
x = -3
0 = m(-3) - 2 Add 2 to both sides.
2 = m(-3) Divide by - 3
2/-3 = m
Now let's see what we have.
y = -2/3x - 2
C is the correct answer
