CAN SOMEONE HELP PLZ AND EXPLAIN BEC IF DONT DO GOOD I CANT GO TO MY DADS HOUSE THIS WEEK END
Galina-37 [17]
Hello!

6.
Since the area is that of a square, you know that all side lengths are the same. 

Area is base times height (A = bh), but since base and height are the same for a square, you get the formula A = a².

A = a^{2}
144 = a^{2}
\sqrt{144} = a
12 = a

The length of the side of a square with an area of 144 in² is 12 in.

7.
Rational number.

8.
This is a right triangle; use the Pythagorean Theorem to find missing lengths of right triangles. Pythagorean Theorem: a² + b² = c², where c is the hypotenuse of the triangle.

Plug in your leg lengths:

a² + b² = c²
8² + x² = 21²
64 + x² = 441
x² = 377
x = 19.4

Pls help you will get brainliest
cupoosta [38]

Answer:

5/6

Step-by-step explanation:

1/6 + 1/6 = 2/6 TYPE A wood

1/4 + 1/4 = 2/4 TYPE B wood

2/6 + 2/4= ...

2/4 reduces to ?/2

That would be 1/2 because 4 divided by 2 is 2 & 2 divided by 2 is 1.

1/2= ?/6

Its 3/6 because we did 2 x 3 to get 6 and we do the same to the number 1. So we do 1 x 3 = 3

Now we have 3/6 + 2/6!

This is very easy now! We just do 2 + 3 which gets 5.

OUR ANSWER IS 5/6!! Hope this helps! plz mark as brainliest!
