Answer:

P = 2(4x - 5)

Step-by-step explanation:

The formula for solving the perimeter of a rectangle is:

P = 2(L + W), or

P = 2L + 2W

Given the length (L) = 3x - 7, and width (W) = x + 2:

Substitute these values into the perimeter formula in order to solve for x and determine the actual dimensions of the given rectangle.

P = 2L + 2W

Use the distributive property of multiplications (over subtraction and addition, respectively), and distribute 2 into each parenthesis:

P = 2(3x - 7) + 2(x + 2)

P = 6x - 14 + 2x + 4

Combine like terms:

P = 8x - 10

Factor out the common term to reduce the algebraic expresssion into its simplest form:

P = 2(4x - 5)

Therefore, the perimeter of the given rectangle in its simplest form is:

P = 2(4x - 5).

seropon [69]

Answer:

Step-by-step explanation:

The response of this would be to say that those people without daytime jobs that are outside the home, are more likely to be home and thus, have more time on their hands to attempt to bake. So basically, the quoted 56% is definitely going to be higher than the population percentage.

4 coffees and 12 lattes. Costs $61
Gala2k [10]

Answer:

Cost of a coffee is <u>$2.5</u> and cost of a latte is <u>$4.25.</u>

Step-by-step explanation:

Let cost of 1 coffee be 'c' and cost of 1 latte be 'l' dollars.

Given:

4 coffees and 12 lattes cost $61.

12 coffees and 7 lattes cost $59.75.

∵ 1 coffee cost = c

∴ 4 coffees cost = 4c and 12 coffee cost = 12c

∵ 1 latte cost = l

∴ 12 lattes cost = 12l and 7 lattes cost = 7l

Now, as per question:

4c+12l=61-----1\\12c+7l=59.75----2

Now, multiplying equation (1) by -3 and adding the result to equation (2). This gives,

-3(4c+12l)=-3(61)\\\\-12c-36l=-183\\12c+7l=59.75\\+\\----------\\0-29l=-123.25\\\\l=\frac{-123.25}{-29}=\$4.25

Now, plug in the value of 'l' in equation 1 to solve for 'c'. This gives,

4c+12(4.25)=61\\\\4c+51=61\\\\4c=61-51\\\\4c=10\\\\c=\frac{10}{4}=\$2.5

Therefore, cost of a coffee is $2.5 and cost of a latte is $4.25.

What is the value of x ​
SVEN [57.7K]

Using the pythagorean theorem, the value of x would be eight. The equation of Pythagorean is

a^2 + b^2 = c^2

(C is the hypotenuse. Hypotenuse being the length of 10) Applying the lengths leaves us with the equation

36 + x^2 = 100.

You then subtract 36 from 100 to get X alone on the opposite side of the equation.

X^2 = 64

Lastly, you take the square root of 64. Therefore, the final answer will be eight.
