HURRY: use Pythagorean theorem to solve for the missing variable

Step-by-step explanation:

The Pythagorean Theorem says: a² + b² = c². In this case the equation would be 4² + 8² = c². Solve to get c² = 80. The square root of 80 is a decimal: 8.9.... You can round up to 9, or leave it at .

Hope it helps!

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
