Acarpenter is refinishing two cupboards. she must add the areas of the cupboards to determine the amount of plywood she needs. the area of the first cupboard is modeled by 3a^2 − 5y + 15, and the area of the second cupboard is modeled by 4a^2 + 5y + 5. identify the polynomial that represents the total area of the cupboards.

You are given the area of both cupboards.

The total area would be found by adding the two areas together:

3a^2 − 5y + 15 + 4a^2 + 5y + 5

Combine like terms:

3a^2 + 4a^2 = 7a^2

-5y + 5y = 0y

15 +5 = 20

The area of both cupboards would be 7a^2+20

da freeck kinda math is this just drop out

step-by-step explanation:

the degrees would remain the same ( the number to the left of the decimal point.

the multiply the decimal by 60 to get the minutes and use the numbers to the left of the decimal point.

then multiply the decimal portion of that by 60 for the seconds and round off as needed.

39 .956652

the 39 remains the degrees.

the minutes = 0.956652 x 60 = 57.39912

the minutes = 57

the seconds = 0.39912 x 60 = 23.95 = 24 ( rounded to nearest tenth)

so 39.956652 = 39 degrees, 57 minutes and 24 seconds

-75.159809

the -75 remains the degrees

the minutes = 0.159809 x 60 = 9.58854

the minutes = 9

the seconds = 0.58854 x 60 = 35.31, rounded to nearest tenth = 35.3 seconds

so -75.159809 = -75 degrees, 9 minutes and 35.3 seconds.

the first coordinate is north or south, since it it positive it is north.

the second number is east or west, because it is negative it is west.

39 degrees, 57 minutes and 24 seconds n

-75 degrees, 9 minutes and 35.3 seconds w
