Answer:
D) Jack made a mistake while squaring first term, 16x^2 - 8x +1
Step-by-step explanation:
we apply (a-b)^2 formula
a= 4x and b= 1
Replace 'a' with 4x and 'b' with 1
(4x)^2 is 16x^2
Jack made a mistake while squaring first term
(4x)^2 is 4^2x^2 that is 16x^2
Answer: $4.20 tip
Step-by-step explanation:
15% of 28 is 4.2
Using a calculator, you can find the value of the tip by multiplying 0.15 by 28.
Length (L): 4w - 5
width (w): w
Perimeter (P) = 2L + 2w
140 = 2(4w - 5) + 2(w)
140 = 8w - 10 + 2w
140 = 10w - 10
150 = 10w
15 = w
Length (L): 4w - 5 = 4(15) - 5 = 60 - 5 = 55
Answer: width= 15meters, length=55 meters
Answer:
Step-by-step explanation:
Explicit Arithmetic Formula: 
a₁ is 1st term in sequence
<em>d</em> is common difference
<em>n</em> is term number
Step 1: Find <em>d</em>
d = 8 - 2 = 6
Step 2: Plug in variables into formula
Answer: His answer is wrong
Explanation:
5(1/5^3) = 5(1^3/5^3) = 5(1/125)
5(5^3) = 5(125)
Let’s compare:
5(1/125) < 5(125)
Because 1/125 is smaller 125
Thus, it is not equal.
