Area of a rectangle = lenght <span> × width

so:
(3x - 5) </span>× 2x = 2x × 3x - 2x × 5 = 6x² - 10x

The answer: 6x² - 10x

Solve the equation 4 x minus 7 space equals space 45 for x.
zimovet [89]

Answer:

x = 13

Step-by-step explanation:

For this problem, we will simply uses properties of addition and multiplication to isolate the x variable for the following equation.

4x - 7 = 45

Now consider the following. First, we must isolate the x term by adding 7 to both sides.

4x - 7 = 45

4x -7 +7 = 45 +7

4x = 52

Second, let's further isolate x by multiplying both sides by 1/4 to create a coefficient of 1 Infront of the x variable.

4x = 52

(1/4) * 4x = 52 * (1/4)

x = 13

Hence, we have solved the equation 4x-7=45 where x=13.

Cheers.

Suppose that a jewelry store tracked the amount of emeralds they sold each week to more accurately estimate how many emeralds to
Ratling [72]

Answer: point estimate = 3.88

Margin of error = 0.63

Step-by-step explanation:

Confidence interval is written in the form,

(Point estimate - margin of error, Point estimate + margin of error)

The sample mean, x is the point estimate for the population mean. Let m represent the margin of error. Since the confidence interval is given as (3.25 , 4.51), it means that

x - m = 3.25

x + m = 4.51

Adding both equations, it becomes

2x = 7.76

x = 7.76/2

x = 3.88

Substituting x = 3.88 into x + m = 4.51, it becomes

3.88 + m = 4.51

m = 4.51 - 3.88

m = 0.63
