Answer: 42.14 cm^2
square:
Area of a square=s^2
A=14^2
A=196
circle (the two semi circles are the same as one circle):
Area of a circle=(pi)(r)^2
divide 14 (diameter) by 2 to find the radius
A=(3.14)(7)^2
A=(3.14)(49)
A=153.86
subtract the area of the two semi circles from the area of the square to get the answer
196-153.86=42.14
6a^3 : 3a = 2a^3-1 = 2a^2
The quotient is 2a^2
Hope it helped
Answer:
Step-by-step explanation:
Identify the slope, m. calculate slope between two known points of the line using the slope formula.
Find the y-intercept. substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
Answer:
4
Step-by-step explanation:
a^3 = 64
therefore , a = 4
Answer:
x2-5x-8=0
Step-by-step explanation:
Two solutions were found :
x =(5-√57)/2=-1.275
x =(5+√57)/2= 6.275
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "x2" was replaced by "x^2".
Step by step solution :
Step 1 :
Trying to factor by splitting the middle term
1.1 Factoring x2-5x-8
The first term is, x2 its coefficient is 1 .
The middle term is, -5x its coefficient is -5 .
The last term, "the constant", is -8
Step-1 : Multiply the coefficient of the first term by the constant 1 • -8 = -8
Step-2 : Find two factors of -8 whose sum equals the coefficient of the middle term, which is -5 .
-8 + 1 = -7
-4+ 2 = -2
-2+ 4 = 2
-1 + 8 = 7
