Answer:
48x
PEMDAS: Do the exponent first 4 times 4 is 16 times that by 3x to get 48x.
Answer:
4
Step-by-step explanation:
12x>48 so divide 48 by 12 to solve for x so x is 4

Answer:
Commutative Property of Multiplication
Step-by-step explanation:
Commutative Property of Multiplication is the switching of the order first factor (multiplicand) and the second factor (multiplier), which does not change the product. For example, 4 × 5 = 5 × 4
-5 × 12 = -60
12 × -5 = -60
Answer:
D.) 8
Step-by-step explanation:
You can use the Pythagorean theorem because this is a right triangle:

a and b are the legs and c is the hypotenuse. The hypotenuse is always the longest side in a right triangle (since it is opposite the biggest angle). The two legs squared have to add up to the hypotenuse squared.
Fill in values:

Simplify exponents:

Isolate the variable. Subtract 225 from both sides:

Find the square root of both sides:

The missing leg length is 8.
