Answer: 
Step-by-step explanation:
You can calculate the area of a kite with the following formula:

Where
is the length of a diagonal and
is the length of the other diagonal.
In this case, you can identify that:

Therefore, the final step is to substitute the values into the formula.
Then, the area is:
You can choose to answer this with fractions or decimals. I'll choose fractions because we won't need calculators. 22 1/2 miles "in" 1/3 hour, means 22 1/2 mi divided by 1/3 hour.
22 1/2 = [(22×2) + 1] ÷ 2 = 45/2
So (45/2)mi ÷ (1/3)hr is the same as (45/2) × (3/1), or (45×3)/2 = 135/2, which is 67 1/2, or 67.5 mi/hr (mph).
Answer:
Part 1) -7 →
Part 2) 3/2 →
Part 3) 1 → 
Part 4) -1/4 → 
Step-by-step explanation:
<u><em>The complete question in the attached figure</em></u>
we know that
To find out the non permissible replacements for y, equate the denominator of each expression equal to 0.
step 1
we have

Equate (2y-3) equal to 0.

solve for y
Adds 3 both sides.

Divide both sides by 2.

therefore
3/2 is the non permissible replacement for y.
step 2
we have

Equate (4y+1) equal to 0.

Subtract 1 both sides

Divide by 4 both sides

therefore
-1/4 is the non permissible replacement for y.
step 3
we have

Equate -5(y-1) equal to 0.

Divide by -5 both sides

Adds 1 both sides

therefore
1 is the non permissible replacement for y.
step 4
we have

Equate -2(y+7) equal to 0.

Divide by -2 both sides

Subtract 7 both sides

therefore
-7 is the non permissible replacement for y
Answer:
4x² + 4x + 1
Step-by-step explanation:
We know that (a + b)² = a² + 2ab + b², therefore, (2x + 1)² = 4x² + 4x + 1.
