Answer:
D.
Step-by-step explanation:
So find what two numbers multiply to 72 and add up to 17
9 and 8
(z + 9)(z + 8)
<em>D. (z + 9)(z + 8)</em>
Let's factor z2+17z+72
z2+17z+72
The middle number is 17 and the last number is 72.
Factoring means we want something like
(z+_)(z+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 17
Multiply together to get 72
Can you think of the two numbers?
Try 8 and 9:
8+9 = 17
8*9 = 72
Fill in the blanks in
with 8 and 9 to get...
so (z + 9)(z + 8)
7/10
28/40=
14/20 =
the true statement is
All parallelograms are quadrilaterals
y-y1=m(x-x1)
y-5=4(x + 5)
y-5=4x+20
5. 5
y = 4x + 25
