Answer:

9.9 inches

Step-by-step explanation:

if the area of ​​the square is 49 we have and know that the base and height are equal we can express it as follows

X is one side of the square.

X * X = 49

X^2 = 49

X = √49

X = 7

by Pythagoras we can calculate the diagonal of the triangle formed by 2 sides of the square with the following expression

Y is the diagonal

7^2 + 7^2 = Y^2

49 + 49 = Y^2

√98 = Y

Y = 9.9

What is the solution to y = x + 2 and y = 3x – 2 and how do you know? PLEASE HELPPPPP! THANK U!
Nutka1998 [239]

Answer:

(2,4)

Step-by-step explanation:

We have the system:

y=x+2

y=3x-2.

This is already setup for substitution.

I'm going to replace my first y with what the second y equals.

That is, I'm going to write 3x-2=x+2.

Time to solve the following for x:

3x-2=x+2

Subtract x on both sides:

2x-2= 2

Add 2 on both sides:

2x. = 4

Divide both sides by 2:

x. = 2

Now that we know x=2 and we have an equation that relates x to y: either y=x+2 or y=3x-2, doesn't matter which we use, we can find y.

So we y=x+2 with x=2 which means y=2+2=4.

So the solution, the intersection, is (2,4).
