Answer:
15
Step-by-step explanation:
Use PEMDAS for this:
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
-4(3-5)+10-3(7+4)+30 = -4(-2)+10-3(11)+30
-4(-2)+10-3(11)+30 = 8+10-33+30
8+10-33+30 = 18-33+30
18-33+30 = -15+30
-15+30 = 15
Answer:
27x - 2
Step-by-step explanation:
First off, we use commutative property to get the like terms together.
(20x + 7x) - (3-5)
Now we can solve the equations inside the parenthesis.
27x - (-2)
Because these aren't like terms, this is as far as we can go. Meaning 27x - 2
is out answer.

Answer:
lol
Step-by-step explanation:
If I were to tell a kid how to use the formula (the SA of a pyramid it looks like):
First, find the area of the base of the figure, using length times width.
Next, find the perimeter of the base by adding up the length of each side of the base.
Multiply the perimeter of the base by the slant height of the figure, which is the line on the side of the figure that is diagonal.
Divide the answer you got from multiplying the perimeter of the base times the slant height of the base by 2.
Now add up the area of the base of the figure with the answer you just got by dividing the perimeter of the base times the slant height by 2.
That is how you use the formula: SA = B + 1/2(P · l)
