A rectangle has a perimeter of 40 in. and a length of 15 in. What is its area?

2 answers:

The perimeter is 2*length + 2*width. 2*length is 30 in. So, 2*width is 10 in. Giving width = 5 inches.

Area = length * width = 15*5 = 75 square inches.

The perimeter is is all 4 sides added together

so 15+ 15 is 30 and 5+5 would be 10 more to make 40

so length is 15in and width is 5in

to find the area

A = l * w

a = 15*5

area is 75in

Factor the algebraic expression below in terms of a single trigonometric function. sin 2x + sin x - 2

Pie

Answer:

The factored form is (sin x +2)(sin x-1)

Step-by-step explanation:

We have been given the trigonometric function $\sin^2 x +\sinx-2$

We can factor this by AC method. In AC method we multiply the term a and c and then write the middle term b in such a way that the sum/difference is equal to the product 'ac'

Using the method, we can write sinx as 2sinx -sinx

$\sin^2 x +2\sinx-\sin x-2$

Now, we group the first two terms and the last two terms

$(\sin^2 x +2\sinx)+(-\sin x-2)$

Now, we take GCF from each group

$\sin x(\sin x +2)-1(\sin x+2)$

Factor out (sinx+2)

$(\sin x +2)(\sin x-1)$

Therefore, the factored form is (sin x +2)(sin x-1)

Answer:

for page 1, the answer is y = x + 1

for page 2, the answer is linear

Step-by-step explanation:

Why is it y = x + 1?

It is y = x + 1 because if you look at the steps, all of them are reasonable for having a multiplication equation. Step 1 has a equation of 1 x 1, step 2 has an equation of 2 x 2, and step 3 has an equation of 3 x 3. So the relationship would be adding +1 to every step and count up from 1 - 3.

--------------------------------------------------------------------------------------------------------------

Why is it linear?

It's linear cause the relationship between x and y is called a linear relationship because the points so plotted all lie on a single straight line.
