You’re going to want to solve what’s inside the parenthesis, 2-3 x 4+5. which is equal to -1 x 9. -1 x 9 is -9. so the final problem is -9 to the second power, which is 81. Hope this helps.

you are making a picture frame in your shop class. two peices of wood are cut to form complementary angles so they fit fit toget

Andrews [41]

Two angles are complementary when their sum is equal to 90°.

So, ( 2x + 39 ) + ( 7x - 21 ) = 90°

9x + 18° = 90°

x = 8°

Putting value of x in the angles given :

( 2x + 39 )° = 2(8°) + 39° = 55°.

( 7x - 21 )° = 7(8°) - 21° = 35°.

Therefore, the angles are 55° and 35°.

Hence, this is the required solution.

nirvana33 [79]

Answer:

Both give - 6=5x

Step-by-step explanation:

First equation 2x-6=7x

When you solve it, it becomes :

2x-6=7x

Subtract 2x both sides

2x-2x-6=7x-2x=

-6=5x

2)5x-6=10

5x-5x-6=10x-5x

-6=5x
