Answer:
x=10
Step-by-step explanation:
9×10=90 That is how I got the answer.
To find the are of a square, we simply square the value of a side
so..
Area = 25 square units
Subtract 5a from both sides
-3=3a+6
Subtract 6 from both sides
-9=3a
Divide by three
a= -9/3 (which is -3)
Remember what you do to one side you must do to the other
Answer:
(x+12)
Step-by-step explanation:
The middle number is 8 and the last number is -48.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 8
Multiply together to get -48
Can you think of the two numbers?
Try -4 and 12:
-4+12 = 8
-4*12 = -48
Fill in the blanks in
(x+_)(x+_)
with -4 and 12 to get...
(x-4)(x+12)
But, since (x-4) isn't an option, the answer would be (x+12)
