We want to solve
x² + 8x + 7 = 0
Factorize the left side.
x² + 8x + 7 = (x + 1)(x + 7)
Therefore
(x + 1)(x + 7) = 0
When (x + 1) = 0, obtain x = -1.
When (x + 7) = 0, obtain x = -7.
The solutions are x = -1 and x = -7
Answer: x = -7 and x = -1.
M-(M•0.16) and M(.84) because the first one you need to multiply to find what 16% of m is then subtract that by m for the second one you subtract .16 from 1 which is .84, then you multiply that by m which will automatically take the 16% decrease which will give you your answer. Both ways give you a 16% decrease of m. I hope this helped
Answer:
673,400
Step-by-step explanation:
Since 22 is not 50 or above you round down to 400

5 : - 1/6 = 0.167 out of 10 = 1.67 out of 100 = 16.7
even number 0.33 out of 10:- 3.3 out of 100:- 33
a prime number 0.5 out of 10: 5 and out of 100:- 50
multipl of 3:- 0/33 out of 10:- 3.3 and out of 100: 33
Answer:
Your answers are correct, but incomplete.
a) should include "supplementary angles"
c) should include "complementary angles"
Step-by-step explanation:
Adjacent angles that form a linear pair are <em>supplementary</em>.
Adjacent angles that make up a right angle are <em>complementary</em>.
The problem asks for all classifications that apply, so these additional classifications should be part of the answers for (a) and (c).
