Answer:

x^2

Step-by-step explanation:

The formula we should use here is (a+b)^2=a^2+2ab+b^2

Using this we should first squared 36, getting us 6

Then divide -12x by 6, getting us -2x

Then we divide-2x by -1, getting us 2x

Lastly we divide 2x by 2 to get x

x is our original factors, but to fit in the equation, we need to square it

Part A.
Using the Pythagorean theorem,
PR² = PQ² +QR²
PR² = (14 ft)² +(6 ft)² = 196 ft² +36 ft² . . . . substitute the given numbers
PR² = 232 ft² . . . . . . . . . . . . . . . . . . . . . . . .find the sum
PR = √(232 ft²) ≈ 15.23 ft . . . . . . . . . . . . . take the square root
The length of rod PR is 15.23 ft.

Part B.
Using the Pythagorean theorem,
PR² = PQ² +QR²
(16 ft)² = (14 ft)² +QR² . . . . . . . substitute the given numbers
256 ft² -196 ft² = QR² . . . . . .. subtract 14²
60 ft² = QR² . . . . . . . . . . . . . . find the sum
√(60 ft²) = QR ≈ 7.75 ft . . . . . take the square root
The new height QR is about 7.75 ft.

When I woke up it was 37° during the day the temperature increase 14° and then begin to decrease when I went to bed it was 29° h

GREYUIT [131]

Answer: The temperature decreased by 22 degrees

Explanation: 37 + 14 is equal to 51. So take 51 and subtract 29 from it since the weather decreased and you get 22 as your answer :)

Can someone help please

lutik1710 [3]

Step-by-step explanation:

For no. 8

2x + 1°+ 33° = 90° { Being complementary angles }

2x + 34° = 90°

2x = 90° - 34°

2x = 56 °

x = 56° / 2

x = 28°

For no. 10

5x + 12 = 6x - 10 ( being vertically opposite angles)

6x - 5x = 12 + 10

x = 22

Hope it will help :)❤
