Aubrey is deciding between two truck rental companies. Company A charges an initial fee of $80 for the rental plus $i per mile driven. Company B charges an initial
fee of $50 for the rental plus $2 per mile driven. Let A represent the amount
Company A would charge if Aubrey drives x miles, and let B represent the amount
Company B would charge if Aubrey drives 2 miles. Write an equation for each
situation, in terms of x, and determine the interval of miles driven, z, for which
Company A is cheaper than Company B.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

answer: b.36 feet

step-by-step explanation:

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to
