Answer:
Length = 29 m
Width = 29 m
Step-by-step explanation:
Let x and y be the length and width of the rectangle, respectively.
The area and perimeter are given by:

Rewriting the area as a function of x:

The value of x for which the derivate of the area function is zero, is the length that maximizes the area:

The value of y is:

Length = 29 m
Width = 29 m
The number is 125 and the equation is 0.8x = 100
Step-by-step explanation:
80% of x is equal to 100.
Write an equation that shows the relationship of 80%, x, and 100
80% = 0.8
0.8x = 100
x = 100/0.8
x = 125
The number is 125 and the equation is 0.8x = 100
Answer:
x = 94°
Step-by-step explanation:
The measure of the chord- chord angle CED is half the sum of the arcs intercepted by the angle and its vertical angle, that is
( arc CD + arc AB ) = 82°
Multiply both sides by 2 to clear the fraction
CD + AB = 164°, that is
x + 70 = 164 ( subtract 70 from both sides )_
x = 94°
Answer:
a) 3 multiplied by x exponential 2 plus two multiplied by y plus half
b) three multiplied by the square of x plus two multiplied y plus one divided by two
c) I just split the equation into parts and started translating them individually to words
