Answer:
-22 ans -46
Step-by-step explanation:
3x – 8 ≤ 46 add 8 to the both sides
3x ≤ 54 divide both sides by 3
x ≤ 18 if x is equal or smaller than 18 the values -22 and -46 can make the inequality true
Step-by-step explanation:
∠A + ∠B + ∠C = 180°
Here the value of ∠B and C is given below...we need to find the value of ∠A ....
a + 120° + 40° = 180°
a + 160° = 180°
a = 160° - 180°
a = 20°
Answer:
b=2
Step-by-step explanation:
-12+3b-1=-5-b
Combine like terms
-13 +3b = -5-b
Add b to each side
-13+3b+b = -5-b+b
-13+4b = -5
Add 13 to each side
-13+13 +4b = -5+13
4b = 8
Divide by 4
4b/4 = 8/4
b = 2
Do you have multiple choice? If so maybe this is the answer : 5(2x^2+1)
