Answer: Is this one question???
Step-by-step explanation:
Answer:
The length is 73 m, and the width is 59 m.
Step-by-step explanation:
perimeter = 2 * length + 2 * width
Let the width = w
length = w + 14
width = w
perimeter = 2 * (w + 14) + 2 * w
perimeter = 2w + 28 + 2w
perimeter = 4w + 28
perimeter = 264
4w + 28 = 264
4w = 236
w = 59
length = w + 14 = 59 + 14 = 73
Answer: The length is 73 m, and the width is 59 m.
Answer:
y=3/2x+5
The slope is 3/2 and the y-intercept is 5
Step-by-step explanation:
Solving for y will give us the slope and y-intercept
Isolate y
2y/2=10+3x/2
y=5+3/2x
The slope is 3/2 and the y-intercept is 5
Graph it by graphing (0,5) and using the slope (up 3 over 2) to put other points
Cos²x+2cos x+1=0
We have to do a change of variable.
cos x=t
Then, we have the next square equation.
t²+2t+1=0
We solve this square equation:
t=[-2⁺₋√(4-4)]/2=-1
if cos x=t then we have that:
cos x=-1
x=cos⁻¹ -1= π radians or 180º.
Answer: x=π (in radians) or x=180º (in degrees).
