True these are all equivalent.
Answer:
Option A, 4(x + 2)(x - 2)
Step-by-step explanation:
<u>Step 1: Pull out a 4
</u>
<em>4(x^2 - 4)
</em>
<u>Step 2: Factor x^2 - 4
</u>
x^2 - 4
<em>(x + 2)(x - 2)
</em>
<u>Step 3: Combine
</u>
<em>4(x + 2)(x - 2)
</em>
Answer: Option A, 4(x + 2)(x - 2)
Answer:D.
-4°F
Step-by-step explanation:
a.
This question is a rather odd way to ask you to find the radius of a circle from its area.
A = π r²
40000 = π r²
r² = 40000/π
r = √(40000/π)
r ≈ 112.8379
Answer: 113 miles
b.
C = 2 π r
754 = 2 π r
r = 754/2π = 377/π
A = π r² = A = π (377/π)² = 377²/π
A ≈ 45241.0658
Answer: 45241 square miles
Answer:
1/3
Step-by-step explanation:
1/3 can be used as an expression that is exactly the same as 2/3x5.
When you multiply 2/3 x 5-
Look here if you need help solving 2/3 X 5: (2/3 x 5/1...is the simplest way to multiply the two, make sure to multiply 2 by 5 and 3 by 1 to get your answer.)(5x2=10...3x1=3)
-you get 10/3. This answer simplified is 1/3. So in the end, 1/3 is a great expression or answer to use as an equivalent to the equation 2/3 x 5.
Hoped this helped! :)
