Answers

The two interior angles that are not supplemantly (adjacent) to the exteroir angle add up to the exterior angle. Therefore we have:

3x+2x=150

5x=150

x=30.

Since it asked for angle BAC, therefore we have:

30 x 2 = 60.

The answer is C.

ALGEBRA! NEED HELP! ~Write a formula for the total surface area of a cube in terms of its edge length x. Explain your reasoning.

Answers

Since each edge's length is x, each face's are would be ${ x }^( 2 )$
And cubes have 6 faces. multiply 6 by ${ x }^( 2 )$ , the formula is : $6{ x }^( 2 )$

surface area of a cube
cube=6 squares
square=2 equal sides
area of square=side^2
surface area of cube=6(area of square)=6side^2
side=x
SA=6x^2

How do you find the x-coordinate of the vertex of a parabola if you only have the equation

Answers

Answer and Explanation:

The vertex formula is derived from the completing-the-square process, just as is the Quadratic Formula. In each case, memorization is probably simpler than completing the square.) For a given quadratic y = ax2 + bx + c, the vertex (h, k) is found by computing h = –b/2a, and then evaluating y at h to find k.
