An integer is 8 more than 5 times another. If the product of the two integers is 36, then find the integers

Harman [31]

Answer:

see below

Step-by-step explanation:

1st: x

2nd: 5x + 8

x(5x + 8) = 36

5x² + 8x = 36

5x² + 8x - 36 = 0

(x - 2)(5x + 18) = 0

(x - 2) = 0

x - 2 = 0

x = 2

1st: x = 2

2nd: 5x + 8 = 5(2) + 8 = 18

(5x + 18) = 0

5x + 18 = 0

5x = -18

x = -3.6

1st: x = -3.6

2nd: 5x + 8 = 5(-3.6) + 8 = -18 + 8 = -10

What is the diagonal of a right triangle

bekas [8.4K]

Answer:

diagonal of a polygon is a line from a vertex to a non-adjacent vertex. So a triangle, the simplest polygon, has no diagonals. You cannot draw a line from one interior angle to any other interior angle that is not also a side of the triangle.

Step-by-step explanation:

To find the length of the diagonal (or hypotenuse) of a right triangle, substitute the lengths of the two perpendicular sides into the formula a2 + b2 = c2, where a and b are the lengths of the perpendicular sides and c is the length of the hypotenuse. Then solve for c
