Complete question :
The sugar maple tree in Joshua's yard is 1/4 the age of the oak tree in his yard. The sugar maple tree is 20 years old. How old is the oak tree?
Answer:
80 years
Step-by-step explanation:
Given that :
Sugar maple tree = 1/4 age of oak tree
Age of sugar maple tree = 20
Age of oak tree = x
20 = 1/4 * x
20 = x / 4
Multiply both sides by 4
20 * 4 = (x / 4) * 4
80 = x
Hence, Age of oak tree = 80 years

Answer:
in one minute they rake leaves working together.
Step-by-step explanation:
If Maya rakes the leaves in x minutes, then, in one minute she rakes leaves.
In the case of Carla, if she rakes the leaves in y minutes, in one minute she rakes leaves.
Therefore, to know the portion of leaves they can rake in one minute working together, we need to sum up both of the portions each one of them rake in one minute, this gives us:
Now, to simplify this expression:
Thus, in one minute they rake leaves.
(f + g)(x) is equal to f(x) + g(x).
So (f + g)(x) = (3x + 5) + (-2x^2 - 5x + 3) = -2x^2 - 2x + 8
which is choice C.
The new length and width is 48in and 40in respectively
<h3>Dilation</h3>
Given the following information
- Width = 25in
- Length = 40in
If the length and the width are dilated by a factor of 1.2, the new length and width is expressed as;
W = 25(1.2) = 30in
L = 40(1.2)
L = 48 in
Hence the new length and width is 48in and 40in respectively
