275,000 km
The moons A, B, C form a right triangle with AC forming a hypotenuse with the diameter of the planet and the distance of both moons from the surface. So add A to the surface, plus the diameter of the planet, plus surface to c.
115000+45000+115000 = 275000
4(3-7x). Since there are 4 sides in a square, you multiply one length by 4 to get the perimeter. 4(3-7x) simplifys to 12-28x.
Answer:
50
Step-by-step explanation:
Use the formula of a trapezoid which is b1 + b2 h/2
8+12=20*5=100/2=50
Answer: 7 packs of forks
Explanation: 6 x 7 is 42. So you’ll have 40 forks for the party with 2 packs left over.
Ah, not quite. The formula for this, I believe, is 2(wl+hl+hw)
Meaning your equation would look like: 2(5*12+8*12+8*5)
Basically, your final answer is 392 for surface area, I believe.
