Find the value of any expressions (within) parentheses first. Then evaluate all powers. Then multiply or (divide) from left to right, and finally add or (subtract) from left to right.
Volume is cubed. If the dimensions are doubled, cube the scale factor:
2^3 = 8
The volume will increase by a scale of 8.
The new volume would be 97 x 8 = 776 ft^3
48 cups of water
1. 4x4= 16 (number of cups in 1 gallon)
2. 16x3= 48 (cups in 1 gallon x the number of gallons she needs)
Answer:
When we add polynomials, we ADD the coefficients but keep the VARIABLES the same.
Step-by-step explanation:
"coefficients" are the numbers right next to a variable. "Variables" are the letters we use for unknown numbers in a math phrase(expression) or sentence(equation).
So you only add the number besides the variable when the terms have the same variable.
Example:
4x + 3m + 5x + 2m
= 9x + 5m
See we only added the 4 and the 5 bc they were both beside the x and we added the 3 and the 2 bc they were both beside the m. See image for another example.
