Don’t say you’re dumb ! we always need help sometimes.
(5x)^2 = ____x^2
distribute the exponent ‘2’ to both terms inside the parentheses.
so it will be (5)^2(x^2)
simplify. 5^2=25, (x^2)=x^2
so the answer is 25x^2
Answer:
Step-by-step explanation:
1. 2
2. 3

4. 2
5. 4
only integers and polynomials are under subtraction.
First, we must find the z-scores for each limit
for 54
z = (54 - 58) / 4 = -1
For this z-score, the area under the curve is 0.1587
for 62
z = (62 - 58) / 4 = 1
The area under the curve is 0.8413
Subtracting the two z-scores:
0.8413 - 0.1587 = 0.6825
Multiplying by 150
150 (0.6825) = 102.39
So, the closest answer is
102
