Two acute angles is the least amount.
Answer:
Step-by-step explanation:
Width of rectangle = 15 cm
width of rectangle is equal to the radius of each semicircle.
radius of each semicircle (r) = 15 cm.
Diameter of each semicircle = 30 cm
Length of rectangle = 3 x 30 = 90 cm.

Answer:
(5x + -4y)(3x + 7y) = 0
Multiply (5x + -4y) * (3x + 7y)
(5x * (3x + 7y) + -4y * (3x + 7y)) = 0
((3x * 5x + 7y * 5x) + -4y * (3x + 7y)) = 0
Reorder the terms:
((35xy + 15x2) + -4y * (3x + 7y)) = 0
((35xy + 15x2) + -4y * (3x + 7y)) = 0
(35xy + 15x2 + (3x * -4y + 7y * -4y)) = 0
(35xy + 15x2 + (-12xy + -28y2)) = 0
Reorder the terms:
(35xy + -12xy + 15x2 + -28y2) = 0
Combine like terms: 35xy + -12xy = 23xy
(23xy + 15x2 + -28y2) = 0
Solving
23xy + 15x2 + -28y2 = 0
Solving for variable 'x'.
Factor a trinomial.
(5x + -4y)(3x + 7y) = 0
Step-by-step explanation:
If you have a table that tells you the (x,y) or coordinates on a graph you can take those coordinates and insert them into the equation y=mx=b. this is the equation to find the slope of a line. If you solve for b in the equation you will have the y intercept. the mx would be the slope.
