Answer:
-4<x<-1
Step-by-step explanation:
To solve the problem, we divide the whole expression by 2:
2x^2 + 10x < –8 → x^2 + 5x < –4
→ x^2 + 5x + 4 < 0
Factorizing
→ (x+4)(x+1) < 0
The expression is ONLY negative when:
x>-4 and x<-1
Therefore, the solution is:
-4<x<-1
Answer:
(B)
Complementary Angles:∠FAD and ∠DAH
Supplementary angles:∠EAC and ∠CAH
Step-by-step explanation:
complimentary-angles add up to 90 degrees
supplementary-angles add up to 180 degrees
21x - 19 = 3x + 17 |add 19 to both sides
21x = 3x + 36 |substract 3x from both sides
18x = 36 |divide both sides by 18
x = 2
Answer:
The answer is 17 2/5
Step-by-step explanation:
To find this, first add all the fractions together.
1/5 + 2/5 + 4/5 = 1 2/5
Now add all the whole numbers together.
8 + 3 + 5 = 16
Now add the two together.
16 + 1 2/5 = 17 2/5
