2(2 – 2x) = –3x A. –4 B. 4 C. 6 D. 0

zlopas [31]

Answer:

$x = 4$

Step-by-step explanation:

Let's solve:

$2(2−2x)=−3x$

Step 1: Simplify both sides of the equation.

$2(2−2x)=−3x \\ (2)(2)+(2)(−2x)=−3x(Distribute) \\ 4+−4x=−3x \\ −4x+4=−3x$

Step 2: Add 3x to both sides.

$−4x+4+3x=−3x+3x \\ −x+4=0$

Step 3: Subtract 4 from both sides.

$−x+4−4=0−4 \\ −x=−4$

Step 4: Divide both sides by -1.

$\frac{ - x}{ - 1} = \frac{ - 4}{ - 1}$

Therefore, the answer will be x = 4.

I need help it's geometry

nekit [7.7K]

Step-by-step explanation:

$\sin(45) = \frac{x}{5} \\ \frac{1}{ \sqrt{2} } = \frac{x}{5} \\ x = \frac{5}{ \sqrt{2} } = 3.535$

$\sin(45) = \frac{y}{5} \\ y = \frac{5}{ \sqrt{2} } = 3.535$

Find the Perimeter & Area for the following circle.

Feliz [49]

Answer:

A = 28.3 cubic inches; P = 20.1 inches

Step-by-step explanation:

Looks like 3/4 of a full circle

The area of a circle is calculated with the formula: $\pi r^{2}$

Since the problem wants pi = 3.14, we use 3.14 instead of pi in the equation.

The radius is given as 3 inches

Area = $3.14*3^{2} = 3.14*9 = 28.26$ cubic inches = 28.3 cubic inches

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

Perimeter is calculated with $2\pi r$ .

But this is 3/4 of a circle with an additional two 3-inch sides

Perimeter = $\frac{3}{4}*2\pi r$ + 2(3) = 14.1 + 6 = 20.1 inches

What are the following factors of x² - 6x +8

d1i1m1o1n [39]

Answer:

2) 4,2

Step-by-step explanation:

Factor by grouping:

$x^2-6x+8\\\\x^2-4x-2x+8\\\\x(x-4)-2(x-4)\\\\(x-2)(x-4)$

Setting the expression equal to 0 and using the Zero Product Property, $x=2$ and $x=4$ , which are the factors of the original polynomial.
