Answer:
x + 10 = x² + 1
(third option listed)
Step-by-step explanation:
assuming that you meant: , because otherwise there would be no equivalent relationships,
(goal: isolate x on one side of the equation whilst having x on the other side of the equation also, like the equation in the question)*
x + 10 = x² + 1
-1 -1
x + 10 - 1 = x²
[find √ of both sides to isolate x]
(equation in problem)
{note: there's no reason to not simplify the equation to , but the question leaves the equation that way, so I didn't simplify it either}
*I used this goal to decide which equations seemed about right, and then trying to test things out in my head

Answer:
C.
Step-by-step explanation:
6≤x<21
Answer:
24 feet
Step-by-step explanation:
Given that:
The length of the rectangle is 6 times the side of a cement square.
Now, this rectangle is formed from 6 squares;
The total area of the path of this square = 96 square feet;
The area of each square now = 96/6 = 16 square feet
Recall that:
Area of a square = S²
where S is the side length
16 = S²
S =
S = 4 ft
The length of the path in feet now is: L × w
= 6 × 4
= 24 feet.
Use the formula:
B refers to the base and H refers to the height of the triangle.
As such, multiply both the base and height of the triangle and divide the answer by 2, to find the area of the triangle.
