Answer:
The original side length of the square was 9 ft
Step-by-step explanation:
Consider that the square was initially of side length "x" (our unknown). Then the sides were all increased by 5 ft, and now the perimeter (addition of all four sides) of the square render 56 ft.
Let's write an equation that represents the addition of the four sides of this new rectangle, and set it equal to 56 ft. Then solve for the unknown "x":
Therefore, the original side of the square was 9 ft.
My mom is a math teacher I will ask her and hope fully she will answer if not sorry...
Answer:
22
Step-by-step explanation:
Just substitute and solve!
(-2)^2 - 7 + (5)^2 = 4 - 7 + 25 = 22
hope this helps! <3
Answer:
C
Step-by-step explanation:
The book at store A is $13.
5% tax means you pay 5 cents extra per dollar.
13*5= 65.
So so far your total is $13.65
The shipping fee is $3
$3+$13.65= $16.65
The book at store B is 15% off, with no extra charge
%15 of $19 is 2.85.
19-2.85 is 16.15

i rushed at the end
We have that
<span>35 + 30s - 45t
case A)
</span>7⋅(5+30s−45t)---> 35+210s-315t-----> is not <span>equivalent
case B)
</span>5(7+6s−9t)----> 35+30s-45t------> is equivalent to 35 + 30s - 45t
case C)
(−35−30s+45t)×(−1)----> 35+30s-45t---> is equivalent to 35 + 30s - 45t
case D)
10×(3.5+3s−4.5)----> 35+30s-45----> is not equivalent
case E)
( 35/2 - 15s + 45/2t) ⋅ (-2)--->-35+30s-45t---> is not equivalent
the answer is
<span>B. 5(7+6s−9t)
C. (−35−30s+45t)×(−1)</span>
