Answer:
Step-by-step explanation:
x = original length of one side
(x-2)² = 20 inches²
x-2 = ±√20 = ±2√5
x = 2±2√5
2-2√5 is an extraneous solution,
so x = 2±2√5 ≈ 6.47 inches

Answer:
13.5
Step-by-step explanation:
x=1.5
6x^2
6(1.5)^2
6(2.25)
=13.5
Answer:
13.5
Step-by-step explanation:
You plug in 1.5 in the x slot, then you would use PEDMAS to solve and finish it!!
(PEDMAS = parenthesis, exponents, division, multiplication, addition, and subtraction) (it depends on whether division or multiplication comes first the same as addition and subtraction)
Hope this helps!!!

Which space mission from Earth traveled to the moon at a faster pace, Apollo 11 or Luna I?
Apollo 11 - 8.35 * 10^1 kilometers/minute
Luna l - 1.76 * 10^2 kilometers/minute
Answer:
Apollo 11 - 8.35 * 10^1 kilometers/minute
Step-by-step explanation:
The primary objective of Apollo 11 was to complete a national goal set by President John F. Kennedy on May 25, 1961: perform a crewed lunar landing and return to Earth.
Additional flight objectives included scientific exploration by the lunar module, or LM, crew; deployment of a television camera to transmit signals to Earth; and deployment of a solar wind composition experiment, seismic experiment package and a Laser Ranging Retroreflector. During the exploration, the two astronauts were to gather samples of lunar-surface materials for return to Earth. They also were to extensively photograph the lunar terrain, the deployed scientific equipment, the LM spacecraft, and each other, both with still and motion picture cameras. This was to be the last Apollo mission to fly a "free-return" trajectory, which would enable a return to Earth with no engine firing, providing a ready abort of the mission at any time prior to lunar orbit insertion.
Answer:
The average speed of Luna I was 1.76 x 10^2 kilometers/minutes. The average speed of Apollo 11 was 8.35 x 10^1.
The average speed of Luna I was greater than the average speed of Apollo 11. So, Luna I traveled at a faster pace than Apollo 11.

Please help I dont know- NO LINKS
Answer:
D
Step-by-step explanation:
yes it is.
start by multiply by 4 to get rid of the fraction on x
4 ([tex]\frac{x}{4}[/tex]) = 4(4) + 4([tex]\frac{2y}{3}[/tex])
x = 16 + 8y/3
Then by 3 to get rid of that one
3(x) = 3(16) + 3([tex]\frac{8y}{3}[/tex])
3x = 48 + 8y
Then subtract 8y from both sides to get
3x - 8y = 48
Answer:
a no
