Answer:
n numbers, because we can use variables like l and w to represent the unknown length and width. Many expressions have more than one variable in them. The volume of a box without a lid is given by the formula V = 4x(10−x)2, where x is a length in inches and Rochelle has invested $2500 in a jewelry making kit.
Step-by-step explanation:
So, to do this, you need to put g*h in parentheses, because you always do parentheses before multiplying i=when solving an equation. So, 8(g*h) will be your expression. Hope it helps030
Answer: package B is the better deal.
Step-by-step explanation:
package A offers free phone and 300 minutes. it will cost 0.12 per minute for each minute over the plan time. Also, package A has a base rate of $39.95. This means that if you average 356 minutes per month in talk time, the cost using package A would be
0.12(356 - 300) + 39.95 = $46.67
package B : phone costs $10 and has 350 minutes of time and 0.08 per minute for each minute over the plan time. Also, package B has a base rate of 35.95 not including the phone. This means that if you average 356 minutes per month in talk time, the cost using package B would be
10 + 0.08(356 - 350) + 35.95 = $46.43
Therefore, package B is the better deal since it is cheaper.
Ok you just replace the x for a 2.
2(2)^4 - 8(2)^2 + 5(2) - 7
2(16) - 8(4) + 5(2) - 7
32 - 32 + 10 - 7
10 - 7

It's A. f(2) = 3.
V = A*h / 3
A = 5*12 / 2 = 60 / 2 = 30 m²
h = 9 m
________________
V = 30*9 / 3
V = 10*9
V = 90 m³
