The equation for this is a^2+b^2=c^2 so your equation would be 7^2+20^2=X
So you square the 7 and the 20 then take the square root of X and you get
X=21.19

Which of the following expressions are equivalent to 2/x^6-y^6? Choose all that apply.
enot [183]

Answer:

A and C

Step-by-step explanation:

Equivalent expressions are expression which when simplified to lowest terms are equal.

Simplify each answer choice to find the expression which simplifies to \frac{2}{x^6-y^6}.

A. Multiply the exponents 3*2 = 6. This is equal.

B. Multiply numerators and denominators. Here the numerator will be 1*1 = 1. It does not equal 2 in the numerator.

C. Here the numerator does equal 2. The denominator multiplies to (x^3 - y^3)(x^3+y^3)\\x^6 -x^3y^3 + x^3y^3 -y^6\\x^6 - y^6

This is equal.

D. The denominator will have three terms here when simplified. This will not be equal.

What is x and y? in the following figure with steps please
Setler79 [48]

Answer:

x: 148 degrees

y: 32 degrees

Step-by-step explanation:

Hello!

To find the unknown values of these angles, we must understand the concept of intersecting lines. When calculating the angles of the intersecting lines, SQP and RQT are identical values since they are on the opposite ends of each other when given these sorts of problems. This helps us find y being 32 degrees.

On the other hand, to find x, we just need to focus on the line PQR. it's a line, which means that it is 180 degrees. Since SQP is 32 degrees, SQR, or the angle that is x, should be 180-32, which is 148
