Answer:  49 square cm

======================================================

For any rectangle, the opposite sides are the same length.

Set the given expressions equal to x and solve to get

2x-1 = x+3

2x-x = 3+1

x = 4

So each opposite side is:

Each side being the same length (7) confirms we have the correct x value.

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

Let's say L = 7 is the length and W is the unknown width.

We'll use the perimeter of a rectangle formula given below with P = 28 as the given perimeter. Solve for W.

P = 2*(L+W)

28 = 2*(7+W)

28/2 = 7+W

14 = 7+W

7+W = 14

W = 14-7

W = 7

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

The rectangle has a length of L = 7 and width of W = 7, so its area is

A = L*W

A = 7*7

A = 49 square cm

Because we have the length and width as the same value, this rectangle is also a square.

Answer:

8

Step-by-step explanation:

add 12+3 is 15, then divide 120 and 15 which is 8

Step-by-step explanation:

When t = 2,

h(2) = 8 + 40.8(2) - 16(2)² = 8 + 81.6 - 64 = 25.6

Therefore the height after 2 sec is 25.6.

Answer:

[tex]h(t) = 8 + 40.8t - {16t}^{2} \\ h(2) = 8 + 40.8(2) - 16 {(2)}^{2} \\ = 8+81.6 - 64 \\ = 89.6 - 64 = \boxed{25.6}[/tex]

After 2 seconds the ball will be at the height of 25.6 unit.

Answer: There is 52.8 ounces of the juice in the cup now.

Step-by-step explanation:

We are given that,

The quantity of juice you initially have = 19.3 ounces

You added 33.5 ounces more to the cup.

Then, By using the addition operation, the total quantity of juice in the cup will be (Juice you initially had) + (additional amount)

i.e. The total quantity of juice in the cup= 19.3 + 33.5 ounces

The total quantity of juice in the cup= 52.8 ounces

Hence, there is 52.8 ounces of the juice in the cup now.

Answer:

10(3^(5-n))

Step-by-step explanation:

The factored form of (x³ - 1) is option C. (x - 1) (x² + x + 1)

Polynomials are mathematical expressions which consist of one or more terms involving variables and coefficients connected with operations like multiplication, subtraction, addition and natural number powers of variables.

Given is a cubic polynomial expression.

Given is x³ - 1.

We have to factorize it.

x³ - 1 = x³ - 1³

We have the algebraic expression identity that,

a³ - b³ = (a - b) (a² + ab + b²)

Using the expression, we get,

x³ - 1³ = (x - 1) (x² + x + 1²)

         = (x - 1) (x² + x + 1)

Hence the correct form is option C.

Answer:

h = 32

Step-by-step explanation:

In the given figure, for the first parallelogram, base is 36 and height is 24 while for the other parallelogram, base is 27 and height is h.

The area of a parallelogram is given by :

A = base × height

So,

The both parallelograms,

[tex]36\times 24=27h\\\\h=\dfrac{36\times 24}{27}\\\\h=32[/tex]

So, the value of h is 32.

Answer:

28.3 (explaination below)! :)

Step-by-step explanation:

Use the formula for cicrumfrence: C=2πr

Radius can be found by splitting the given number in half, (unless you were given the radius already, then you'd just multiply by 2).

Plug in our numbers. C= 2π4.5

Then, multiply.

You'd get 28.27433388230814.

Rounding to the first decimal place, you'd have a final answer of  28.3.

Answer:

x=70

Step-by-step explanation:

First subtract 30 from 180

180-30=150

Subtract 10 from 150

150-10=140

Divide 140 and 2

140÷2=70

Answer:

x=70

Step-by-step explanation:

angles on a straight line add to 180

so first you do 180-30 which equals to 150

this means that 2x+10=150

take away 10 from both sides and your left with

2x=140

since you are finding x

you divide both sides by 2

x=70
