Answer:
The answer to your question is the letter A. 20 ft²
Step-by-step explanation:
Data
length of a side = 10 ft
length of the diameter = 10 ft
length of the radius = 5 ft
Process
1.- Calculate the area of the square
Area of the square = side x side
= 10 x 10
= 100 ft²
2.- Calculate the area of the circle
Area = πr²
Area of the circle = (3.14)(5)²
Area of the circle = 78.5 ft²
3.- Calculate the remaining area
Remaining area = 100 - 78.5
Remaining area = 21.5 ft² ≈ 20 ft²
These lines are perpendicular because y = -6 is a horizontal line with a slope of 0 and x = 6 is a vertical line with an undefined slope
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
