Step-by-step explanation:
it does not have any variables and it does not have an equal sign, so it is an expression
Answer: B
Step-by-step explanation: The line crosses the Y axis at 3
7.) 4x greater because 8*8=64 and 4*4=16 64/16=4
8.) 22 because 70-13-13=44/2=22
9.) 32 because the square root of 64 is 8 so each side is 8 square feet
10.) The rectangle is an 8 by 5 and the perimeter is 26
-3x + 9 - 4 = x + 3 + 2x
-3x + 9 - 4 = 3x + 3
9 - 4 = 6x + 3
5 = 6x + 3
2 = 6x
1/3 = x
We break apart the first numer:
10+8
the second:
20+1
and add like this:
18+21=10+8 + 20+1
now, we can mix up the order:
18+21=10+8 + 20+1= 10+20 + 8+1
add the parts:
18+21=10+8 + 20+1= 10+20 + 8+1=30+9=39
