Malik asked his teacher if there was a way to check his answer after writing equivalent expressions. What should be his teacher’

s response? Choose a number to substitute for the variable. Find the value of each expression. If the values are even, the expressions are equivalent. Substitute a number for the variable. If the simplified expressions have the same value, the expressions are equivalent. Multiply each expression by the same number. If the expressions are equal, the expressions are equivalent. Add a number to each expression. If the simplified expressions are equal, the expressions are equivalent.

Step-by-step explanation:

a squared + b squared = c squared

2. 5 squared = 25, 11 squared = 121, 25 + 121 = 146, the squre root of 146 is 12.08

3.19 squared = 361, 421 - 361 = 60 60 squared = 7.74

On square PQRS below, if Q is located at (7,0) and R is located at (5,-8) what is the length of SR
jenyasd209 [6]

the length of SR is 2\sqrt{17} .

<u>Step-by-step explanation:</u>

Here we have , On square PQRS below, if Q is located at (7,0) and R is located at (5,-8) . We need to find Length of side SR . Let's find out:

We know  that  , In a square there are  4 sides , and length of every side is same . So side length of SR = side length of QR . Now , Let's find side length of QR .

We know that distance between two points Q(x_1,y_1),R(x_2,y_2) given by :

⇒ QR = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Two points given are Q(7,0), R(5,-8) :

⇒ QR = \sqrt{5-7)^2+(-8-0)^2}

⇒ QR = \sqrt{(2)^2+(-8)^2}

⇒ QR = \sqrt{4+64}

⇒ QR = \sqrt{68}

⇒ QR = 2\sqrt{17}

But QR=SR , Therefore , the length of SR is 2\sqrt{17} .
