Hello!

You can use the Pythagorean Theorem

c is the hypotenuse which is the side across the right angle

a and b are the other sides

Put in the values you know

Square the numbers

Subtract 25 from both sides

Take the square root of both sides

a = 10.9

The answer is D) 10.9 centimeters

Hope this helps!

Hello!

You can use the Pythagorean Theorem

a^{2} + b^{2} = c^{2}

c is the hypotenuse which is the side across the right angle
a and b are the other sides

Put in the values you know

a^{2} + 5^{2} = 12^{2}

Square the numbers

a^{2} + 25 = 144

Subtract 25 from both sides

a^{2} = 119

Take the square root of both sides

a = 10.9

The answer is D) 10.9 centimeters

Hope this helps!

Width:

2w = p - 2l

2w = (8l + 2) - 2l

HELP HOW DO I SOLVE THE FOLLOWING? PLEASE HELP
levacccp [35]
f(x) = \sqrt[3]{2x - 1} \\f(14) = \sqrt[3]{2(14) - 1} \\f(14) = \sqrt[3]{28 - 1} \\f(14) = \sqrt[3]{27} \\f(14) = 3

f(x) = \sqrt[3]{2x - 1} \\f(-62) = \sqrt[3]{2(-62) - 1} \\f(-62) = \sqrt[3]{-124 - 1} \\f(-62) = \sqrt[3]{-125} \\f(-62) = -5

f(x) = \sqrt[3]{2x - 1} \\f(20) = \sqrt[3]{2(20) - 1} \\f(20) = \sqrt[3]{40 - 1} \\f(20) = \sqrt[3]{39}
