Answer:
(6x+4)^2=16; x=0
Step-by-step explanation:
Set it up like this, going from words on the page to letters and variables:
-3(2x+5) = -57. Twice a number is 2x, increased by 5 is 2x+5, and that is multiplied by -3 to get a total of -57. Distribute the -3 into the parenthesis to get -6x - 15 = -57. Move the 15 over by addition to get -6x = -42. Divide both sides by -6 to get that x = 7

Answer:
The perimeter is 44cm.
Step-by-step explanation:
The perimeter is the length of all the sides. So, to calculate the perimeter, add all the sides together.
However, there are two sides that do not have a measure written. So we must first calculate them:
The long vertical side can be calculated by subtracting the other vertical sides by the long bottom side:
14 - 5 - 6 = 3cm
The missing horizontal side can be found by subtracting the leftmost side by the shorter horizontal sides:
8 - 3 - 2 = 3cm
Now, add them all together:
8cm + 5cm + 3cm + 3cm + 3cm + 6cm + 2cm + 14cm = 44cm
