Answer:
x=9 x=-1
Step-by-step explanation:
2(x-4)^2=50
Divide each side by 2
2/2(x-4)^2=50/2
(x-4)^2=25
Take the square root of each side
sqrt((x-4)^2)=sqrt(25)
x-4 = ±5
x-4 =5 x-4 = -5
Add 4 to each side
x-4+4=5+4 x-4+4 = -5+4
Angle of elevation is the angle from the banana up to the plane, which is 23 degrees.
The distance from the banana to the plane is the angle line labeled x.
The distance from the plane to the ground is the vertical line labeled 2500m.
Nothing important would be j.

Answer:
35 feet square
Step-by-step explanation:
The greatest common factor of 70 and 525 is 35. The largest square plot can be 35 feet on a side.
70 = 2·35
525 = 15·35

I like to find the GCD (greatest common divisor) using Euclid's algorithm. We find the remainder when dividing the larger by the smaller. When that remainder is not zero, we replace the larger number with the remainder, and repeat. When the remainder is zero, the divisor is the GCD.
525/70 = 7 r 35
70/35 = 2 r 0 . . . . . 35 is the GCD
Answer:
We just have to do 15 ÷ 15/4 = 15 * 4/15 = 4.
Divide the figure into a triangle on the left and a rectangle on the right. You know the side lengths of the rectangle are 3 x 10, so multiply to get the area of the rectangle. Next, find the area of the triangle. The area of a triangle is given by 1/2bh, where b is the base and h is the height. Because you know the short side of the rectangle is 3, subtract 3 from 5 to get the base of the triangle. then multiply that by 10, the height, and divide by 2 to get the area of the triangle. Then just add up the area of the triangle and the area of the rectangle to get your answer :)
