How do you know that the answer is 40?Maria wants to draw a painting with an are of 40 square inches. If she drew her painting on 1-inch grid paper how many squares would the painting cover?

Explain

Answers

With grid paper, each square is the same area. If the grid paper used is one-inch grid paper, that means each square on the paper is one square inch.Therefore, if Maria wants to draw something that is 40 square inches, it will fill 40 squares on the one-inch grid paper.

$\large\boxed{(x+y)^2:(x-y)^2=49}$

Step-by-step explanation:

Find the measure of the complement of angle KMA.

Answers

we have a few steps to figure the complement of ∠KMA. We know what is given will equal a straight line so we set the two expressions to equal 180.

(2x - 3) + (7x + 21) = 180
2x - 3 + 7x + 21 = 180 (combine like terms)
9x + 18 = 180 (subtract 18 from both sides)
9x = 162 (divide both sides by 9)
x = 18 (use this to find the value of ∠KMA)

2x - 3
2(18) - 3
36 - 3
33 ∠KMA is 33°

to find the complement, we subtract the 33 from 90 and we get the complement to ∠KMA is 57°

Graph the first equation, which has slope = 2 and y-intercept = −3, graph the second equation, which has slope = 4 and y-intercept = 1, and find the point of intersection of the two lines.

Answers

The answer is A) On a graph, find the point of intersection of two lines; the first line has y-intercept = 5 and slope = −3, and the second line has y-intercept = 2 and slope = 1.

pls mark me brainliest

You put -3. Over on -762 and the slope (m) and -43
