What is the length of the hypotenuse of a right triangle if each of the two legs is 4 units?
a) the square root of 8 units
b) 4 units
c) the square root of 32 units
d) 8 units

Use pythagorean theorem formula: (a^2+b^2)=c^2 - c is hypotenuse - a and b are the legs

Plug in numbers.

(4*4)+(4*4)=32

Now we need to find the square root of 32 units since that number is our c^2

C

8

step-by-step explanation:

this is a subtraction problem.

10 - 2 = 8

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
