58. 2 x 7 = 14 for the steps and top, 2 x 3 = 6 for the back, 2 x 4 = 8 for the bottom, ( ( 3 x 2 ) + 3 ) x 2 = 18 for the two sides.
Altogether, the surface area is:
= 14 + 6 + 8 + 18 = 46 units²

<span>before answering this question, we should know the properties of angles and parallel lines. For example, two angles are called interior alternate angles, if each angle is created by the existence of two parallel lines and a an another line called transversal. As for our case, 3 and 5 are alternate angles, so meas 3 = meas 5. It verifies Z test when we look at the figure.</span>
Answer:
(2 ^2 ⋅3⋅7x 12 )
Step-by-step explanation:
Answer:
x=9 B
Step-by-step explanation:
3x=27
divide both sides by 3 to get the x alone
28/3=9
