Line B is incorrect cause he did not do like terms
Answer:
(4a - 5)(4a + 5)
Step-by-step explanation:
Assuming you require to factor the expression
Given
16a² - 25 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
16a² - 25
= (4a)² - 5²
= (4a - 5)(4a + 5) ← in factored form
Answer:
2i + 6
Step-by-step explanation:
4-2 = 2
6-3 = 3
2 * 3 = 6
2i
If your choices are the following:
a. a(t) = t^4 + 2t
<span>b. a(t) = t^4 + 2t + 3t^(5/2) </span>
<span>c. a(t) = t^4 - 3t^(5/2) + 2t` </span>
<span>d. a(t) = t^4 + 2t - 2t^(1/2) + sqrt(t)
The answer is letter c.</span>a(t) = t^4 - 3t^(5/2) + 2t`
Solution:
Area= length times width
Then to get the time, a=a(t), l=l(t), and w=w(t)
So, if Area= l times width
a(t)= l(t) • w(t)
a(t)=[t^2-squrt(t)] • [<span>t^2-2t^1/2]
</span><span>a(t) = [t^2 - t^(1/2)] • [t^2 - 2t^(1/2)]
</span><span>=t^4 - 3t^(5/2) + 2t </span>
Area of a rectangle equals l×w
(5x-3)(x+7)
Distribution
5x2+35x-3x-21
5x2+32x-21
The answer is c
