f(2)=36
Basically, the x becomes two so it changes to six squared
<span>-3a+7b=-16
-9a+5b=16
multiply 1st equation by 3
</span><span>-9a + 21b = -48
-9a + 5b =16
------------------------subtract
16b = -64
b = - 4
</span>-3a+7b=-16
-3a+7(-4)=-16
-3a = -16 +28
-3a = 12
a = -4
answer
a. first choice
<span>The values of a and b are both equal to –4.</span>
If i’m seeing correctly, the cursor is covering a number for the measure of angle BCD. assuming that ABE is the same, as it looks, then it should be the number your cursor is covering.
Answer:
7.2 in² or 7.2 inches squared
Step-by-step explanation:
Area is a measure of how much space there is on a flat surface.
To find the area, just multiply the length and width of the figure.
2 × 3.6 is 7.2
When you find the area, you have to square it.
So, the answer is 7.2 in², or 7.2 inches squared
