Answer: x=-3

Step-by-step explanation:

First let's eliminate the square root

$(\sqrt{x^2-5x+2})^2=(\sqrt{x^2+17})^2\\x^2-5x+2=x^2+17$

Now subtract $x^2\\$ from both sides

$x^2-5x+2-x^2=x^2+17-x^2\\-5x+2=17$

Subtract 2 from both sides

$-5x+2-2=17-2\\-5x=15$

Finally divide both sides by -5

$\frac{-5x}{-5} =\frac{15}{-5} \\x=-3$

X=-3 is your answer

simplify the equation, cancel equal terms, move constant to the right, calculate, divide both sides !!!!

Find the volume of the prism.<br> 9km 8km 6km

HACTEHA [7]

The correct answer is option B which is the volume of the prism is 216 km³.

<h3>What is the volume of the prism?</h3>

A prism is a three-dimensional solid with a triangular base called a triangular prism. The volume of the triangular prism is equal to the product of the area of the base and the height of the prism.

The volume of the prism will be calculated by using the formula below:-

V = Area of the base x Height

Since the base is a right-angle triangle so we will calculate the area of the right-angle triangle.

V = Area of the triangle x Height

V = ( 1/2 ) x 8 x 6 x ( 9 )

V = 216 km²

Therefore the correct answer is option B which is the volume of the prism is 216 km³.

Write the equation of the line that passes through the point (-2, 7) and is PARALLEL to the line y = -4x + 1.

qwelly [4]

Answer:

The equation is $y=x-9$

Step-by-step explanation:

If we want a line parallel to the line in the problem it will have the same slope. The equation given in the problem is already in slope intercept form so we can take the slope for the new equation directly from this equation.

The slope-intercept form of a linear equation is: $y=mx+b$
