Answer:
x = -0.76
Step-by-step explanation:
-7x + 29 = 6 (8 + 3x)
-7x + 29 = 48 + 18x
-7x = 48-29 + 18x
-7x = 19 + 18x
-7x-18x = 19
-25x = 19
x = 19/-25
x = -0.76
Answer:
B. 8x - 3
C. 8x + 12
Step-by-step explanation:
64 is a perfect square, meaning it has two factors that are identical (8), and 36 is also a perfect square, but in this case, you don't see two 6's in the answer choices.
12 and -3 give you a product of -36, so your answer choices would be:
(8x - 3) (8x + 12)
If you're unsure, you can multiply them together to check if they come out to the unfactorized expression.
2^9 = 2 x 2 x2 x 2 x 2 x 2 x2 x 2 x 2 = 512
2 ^9 = 512
The 3 inside angles need to equal 180.
Subtract E from 180 to find the sum of the other two angles:
180 - 104 = 76
Now because EF ≅ DE , angle D and F would be the same so divide 76 by 2
Angle D = 38
Answer:
5
Step-by-step explanation:
10 / 2 = 5
5 times smaller also means 1/5 as big.
