7. a) Determine the error, if any, in the solution to this equation. Describe in words, in detail.
-6(2x – 5) = 4x – 2(x + 3)
- 12x + 30 = 4x – 2x – 6
-12x – 12x + 30 = 6x – 12x – 6
30 = -6x - 6
30 + 6 = -6x – 6 + 6
36 = - 6x
36 -6x
-6 -6
-6= x

b) If an error, solve the equation correctly.

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.

x-3y=4

step-by-step e

hey there : ) your answer would be a.

step-by-step explanation:

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.
