The slope is 3/2.
The y-intercept is 3.
Answer:
706.5 ft²
Step-by-step explanation:
A. Width of the rectangle
The formula for the area of a rectangle is
A = lw
But, l = 3w, so,
A = (3w)w
= 3w² = 12
w² = 4 Divided each side by 3
w = 2 ft Took the square root of each side
B. Length of rectangle
l = 3w = 6 ft
C. Diameter of circle
d = 5l = 5 × 6 = 30 ft
D. Radius of circle
d = 2r
r = d/2 Divided each side by 2
r = 30/2 = 15 ft
E. Area of circle
A = πr² = 3.14 × 15² = 3.14 × 225 = 706.5 ft²
The area of the circle is 706.5 ft².

Answer:$25.80
Step-by-step explanation:
6.45/5 = 1.29
1.29 x 20 =25.80
Answer:
Y = 26
W = 73
X = 81
Step-by-step explanation:
∠W = 3∠Y - 5
∠X = ∠W + 8 = 3∠Y - 5 + 8 = 3∠Y + 3
∠Y + ∠W + ∠X = 180
substitute in the formula
Y + (3Y - 5) + (3Y + 3) = 180
7Y -2 = 180
7Y = 182
Y = 26
W = 3(26) - 5 = 73
X = 73 + 8 = 81
