Answer:
m = 1
Step-by-step explanation:
<u>2(m+2) - (2m-1)</u> = <u>5</u>
(m+2)(2m-1) 3
2m² -1m + 4m -2 = 3
2m² + 3m - 5 = 0
(2m+5)(m-1) = 0
m = 1 This is the only value that satisfies the equation
m = -5/2
Answer:
Step-by-step explanation:
Semicircle:
Shaded area of semicircle = area of outer semicircle - area of inner semicircle
Outer semicircle:
d = 40 m r = 40/2 = 20m
Area of outer semicircle = πr²
= 3.14*20*20
= 1256 m²
Inner semicircle:
d = 30 m r = 30/2 = 15 m
Area of outer semicircle = πr²
= 3.14*15*15
= 706.5 m²
Shaded area of semicircle = 1256 - 706.5 = 549.5 m²
Shaded area of semicircle in both sides = 2 * 549.5 = 1099 m²
<u>Rectangle on both sides:</u>
Length = 50 m
width = 30 m
Area of shaded rectangles on both sides = 2* (length *width)
= 2* 50 * 30
= 3000 m²
Shaded area = 1099 + 3000 = 4099 m²
Answer:
y + 20 > -30
Step-by-step explanation:
the solution set of y + 20 > -30 is
y> -50
-25 is greater than -50.
Answer:
I actualy can't see
Step-by-step explanation:
Absolute value is just whatever number wether positive or negitive, and made positive.
This is because aboslust value means the distance from zero, and distance is always positive.
