Answer:
Length = 34 and Width = 30
Step-by-step explanation:
This is a simple system of equation that is mainly solved using substitution, so keep in mind the following key points:
- Rectangle's Perimeter is 128 ft.
- "the garden is 4 feet longer than it is wide," this simply means that the Length is 4 feet longer than the Width: which algebraically translates to
- Perimeter formula for Rectangle is
First, we find the Width by plugging the given values in the formula:
All we did here was substituting 4 + W for L to find the Width.
Now, to find the Length we plug in the value of W and solve for L:
Tip: always sketch a rough geometrical diagram of word problems, it helps. (Refer to the diagram attached)

Answer:
The value of x is 10.5 units.
Step-by-step explanation:
Given:
ABCD is a parallelogram.
AB =
BC =
CD =
We need to find the value of x.
Now the Definition of Parallelogram states that;
"A parallelogram is a quadrilateral with two pairs of parallel sides. The opposite sides of a parallelogram are equal in length and the opposite angles are equal in measure."
Hence from Above definition we can say that;
since these are the opposite sides of parallelogram.
Now Substituting the given values we get;
Now solving the equation we get;
Combining the like terms first.
Now using addition and subtraction property of equality we get;
Now using Division Property we will divide 2 on both side we get;
Hence the value of x is 10.5 units.
Answer:
20/7 dollars per hour
Step-by-step explanation:
He pays 10 dollars per 3 1/2 hours. To find the unit rate, we divide the two.
10 / (3 1/2) =
10 / (7/2) =
(10/1) x (2/7) =
20/7
Answer:
11x^2-8x-14
Step-by-step explanation:
(2x^2- 8x– 6)+(9x^2-8) = 11x^2-8x-14
