Answer:
P = 2x + 2y + 8
Step-by-step explanation:
The perimeter (P) of a rectangle is calculated as
P = 2(l + w) ← l is length and w is width , then
P = 2(x + 5 + y - 1) ← distribute parenthesis
= 2x + 10 + 2y - 2 ← collect like terms
= 2x + 2y + 8
The average distance of Neptune from the Sun is 2,795,084,800 miles or 4,498,252,900 kilometers. Because its orbit is elliptical, its distance from the Sun changes depending on where it is in its orbit. The closest Neptune gets to the Sun is 2,771,087,000 miles or 4,459,630,000 kilometers. The farthest it gets from the Sun is 2,819,080,000 miles or 4,536,870,000 kilometers.
Answer:
angle c should be 65 as for the sides i don't know sorry
Step-by-step explanation:
A single angle is generally not considered to be supplementary. Supplementary angles are angles that equal 180° when they are added together. For example, 70° and 110° are supplementary because they equal 180°.
However, I guess the supplementary angle can be the angle that must be added to another to total 180°. For example, 80° is the supplementary angle of 100°.
