Answer:
x = 10°; Angle A = 84°
Step-by-step explanation:
Angle A + Angle B = 180
5x + 34 + 2x + 76 = 180
7x + 110 = 180
7x = 70
x = 10
Angle A: 5(10) + 34 = 50 + 34 = 84°
Answer:
Step-by-step explanation:
(((22•5ax2) + 25ax) + 15a) - 5 = 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
20ax2 + 25ax + 15a - 5 =
5 • (4ax2 + 5ax + 3a - 1)
Equation at the end of step 3 :
5 • (4ax2 + 5ax + 3a - 1) = 0
Step 4 :
Equations which are never true :
4.1 Solve : 5 = 0
Answer:
D. 7.29.
Step-by-step explanation:
For a Normal Distribution:
Q1 = mean - (0.675) * standard deviation
= 8.5 - 0.675*1.8
= 7.285.
Simplify 4^4 to 256
256 + 1/2 = 256.5
Simplify 256 + 1/2 to 513/2
513/2 = 256.5
Since both sides equal, there are infinitely many solutions.
