Hello,
if 2x²=54 then (2x)²=4x²=2*2x=2*54=108
Answer:
Complement: 118°. Supplement: 28°
Step-by-step explanation:
To determine the supplement, subtract the given angle from 180.
180 - 62 = 118
To determine the complement, subtract the given angle from 90.
90 - 62 = 28
Answer:
Completing the square.
Step-by-step explanation:
since there is no "a" term and the bx term is even, completing the square is your best bet.
Answer:
(y^2)/4 square meters
Step-by-step explanation:
For a perimeter length of x, the side of a square will be x/4 and its area will be (x/4)^2.
If one side of the square is shortened by y/2 and the adjacent side is lengthened by y/2, then the difference in side lengths will be y. The area of the resulting rectangle will be ...
(x/4 -y/2)(x/4 +y/2) = (x/4)^2 -(y/2)^2
That is, the difference in area between the square and the rectangle is ...
(x/4)^2 - ((x/4)^2 -(y/2)^2) = (y/2)^2 = y^2/4
The positive difference between the area of the square region and the area of the rectangular region is y^2/4 square meters.
Since the two lines are parallel, the angle labeled 130 is congruent to the angle labeled x+ 136 so you can set them equal to each other
130 = x + 136
subtract 136 from both sides
x = -6
