The answer is 36, because when you divide 80/20 it is going to be 4 and 9*4 is 36!
Answer:
Maybe the first?
Step-by-step explanation:
If the first choice was 8 yards by 4 yards, then it would be correct.
A reduction means a scale factor of less than 1, while the second, third, and fourth choices have scale factors of 6, 12, and 2 respectively.
Answer:
y = (2x + 3)(2x + 3) = (2x + 3)²
Step-by-step explanation:
We are given a quadratic function and we have to write it in factored form.
y = 9 + 12x + 4x²
y = 4x² + 12x + 9
We can break the mid-term in such a way that when they are multiplied, the factors give a product of 36x² and when added, they give a result of 12x, as show below:
y = 4x² + 6x + 6x + 9
Taking 2x common from the first two variables and 3 from the second two
y = 2x(2x + 3) + 3(2x + 3)
Taking 2x+3 common
y = (2x + 3)(2x + 3) = (2x + 3)²
Answer: ![\frac{3}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B10%7D)
Step-by-step explanation:
Given
Sean paints
of a fence in 1 hour
Sean paints
part less in the second hour
So, fraction he paints in the second hour = ![\frac{8}{15}-\frac{3}{10}=\frac{16-9}{30}=\frac{7}{30}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B15%7D-%5Cfrac%7B3%7D%7B10%7D%3D%5Cfrac%7B16-9%7D%7B30%7D%3D%5Cfrac%7B7%7D%7B30%7D)
Paint in 2 hours = ![\frac{8}{15}+\frac{7}{30}=\frac{16-7}{30}=\frac{9}{30}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B15%7D%2B%5Cfrac%7B7%7D%7B30%7D%3D%5Cfrac%7B16-7%7D%7B30%7D%3D%5Cfrac%7B9%7D%7B30%7D)
=![\frac{3}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B10%7D)
No, he did not finish his job
