Terms with the same variable and the same exponent are called like terms
Answer:
The side lengths are 10 by 7
Step-by-step explanation:
The area of a rectangle is
A = l*w
70 = (x - 11)(x - 8)
FOIL
70 = x^2 -8x-11x+88
Combine like terms
70 = x^2 -19x +88
Subtract 70 from each side
0 = x^2 -19x +88-70
0 = x^2 -19x+18
Factor
What number multiplies to 18 and adds to -19
-18*-1 =18
-18-1 = -19
0=(x-18)(x-1)
Using the zero product property
x-18=0 x-1=0
x=18 x=1
But x cannot x=1 because then the side lengths would be negative
x-18 = 10
x-11 = 7
The side lengths are 10 by 7
Answer:

Step-by-step explanation:
Answer:
answer will be 70
Step-by-step explanation:
First of all simplify this 24-45
youll get -21
then, simplify-21-9
you'll get -30
and finally simplify-30+100
you'll get 70
Answer:
<h3>The number is 12</h3>
Step-by-step explanation:
Let the number be x
Half a number is written as 1/2x
So we have
Four times the sum of half a number and 6 is 48 is written as
Divide both sides by 2
That's
We have the final answer as
<h3>x = 12</h3>
