7.25(40) + (7.25 * 1.5) * 2.5 = 290 + 10.875(2.5) =
290 + 27.1875 = 317.1875 rounds to 317.19
Answer:
A
Step-by-step explanation:
Answer: 20.48
Step-by-step explanation:
use the pythagorean theorem for the diagnal sides
3^2+3^2=c^2
9+9=c^2
18=c^2
this gives you 4.24
now add 6+6+4.24+4.24 to get 20.48
Answer: The five exponent properties are
Product of Powers: When you are multiplying like terms with exponents, use the product of powers rule as a shortcut to finding the answer. It states that when you are multiplying two terms that have the same base, just add their exponents to find your answer.
Power to a Power.: When raising a power to a power in an exponential expression, you find the new power by multiplying the two powers together. ... Then multiply the two expressions together. You get to see multiplying exponents (raising a power to a power) and adding exponents (multiplying same bases).
Quotient of Powers.: When you are dividing like terms with exponents, use the Quotient of Powers Rule to simplify the problem. This rule states that when you are dividing terms that have the same base, just subtract their exponents to find your answer. The key is to only subtract those exponents whose bases are the same.
Power of a Product: The Power of a Product rule is another way to simplify exponents. ... When you have a number or variable raised to a power, it is called the base, while the superscript number, or the number after the '^' mark, is called the exponent or power.
Power of a Quotient.: The Power of a Quotient rule is another way you can simplify an algebraic expression with exponents. When you have a number or variable raised to a power, the number (or variable) is called the base, while the superscript number is called the exponent or power
You can use these any way you want to rewrite an equation.

Reorder the terms:
18 = -6 + m
Solving
18 = -6 + m
Solving for variable 'm'.
Add '-1m' to each side of the equation.
18 + -1m = -6 + m + -1m
Combine like terms: m + -1m = 0
18 + -1m = -6 + 0
18 + -1m = -6
Add '-18' to each side of the equation.
18 + -18 + -1m = -6 + -18
Combine like terms: 18 + -18 = 0
0 + -1m = -6 + -18
-1m = -6 + -18
Combine like terms: -6 + -18 = -24
-1m = -24
Divide each side by '-1'.
m = 24
