Answer:
width = 8 inches
length = 10 inches
Step-by-step explanation:
width= 12/1.5
= 8
length = 15/1.5
= 10
-3x + 7x = -12
You need to add like terms.
4x = -12
Then, you need to divide both side by 4.
x = -3
So the answer is:
A) x = -3

Answer:
(x+5)(x+7)
Step-by-step explanation:
Let's factor x2+12x+35
x2+12x+35
The middle number is 12 and the last number is 35.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 12
Multiply together to get 35
Can you think of the two numbers?
Try 5 and 7:
5+7 = 12
5*7 = 35
Fill in the blanks in
(x+_)(x+_)
with 5 and 7 to get...
(x+5)(x+7)
Answer:
(x+5)(x+7)
