Answer:
Step-by-step explanation:
Well.. First of all, the question says that we are working with a rectangle..
So, the rectangle has a length and width. I'll call them L and w.
Look at this phrase: " length that is one foot less than twice its width"
it means, in a algebraic language: L = 2w - 1
Let's analysis the next phrase: "it the area of the rectangle is 91 square feet"
So, A = 91 ft²
But you have to remember that the rectangle area is a product of L and w.
L x w = 91
They are the following equations that you could be used to solve the system of equations.
Now, you have a system of equations and I suggest you to solve it using the substituition method.
L = 2w - 1
L x w = 91
Answer:
x=65*
Step-by-step explanation:
theres a small rectangle near x and it means that the angle is 90*
and the upper angle is 180
180+90+25+x=360*
x=65*
Answer:
32
Step-by-step explanation:
Answer:
x = 5 and -2
Step-by-step explanation:
Given the function of x to be;
f(x) = (x-5)(x+2)/x+1
The value of x that will make the function zero can be calculated for by equating the given function to zero first to have;
If f(x) = 0, then;
(x-5)(x+2)/x+1 = 0
Cross multiplying;
(x-5)(x+2) = 0
(x-5) = 0 and x+2 = 0
x = 5 and x = -2
The value of x that will make the function zero is therefore 5 and -2
Answer:
Step-by-step explanation:
Since, By the given diagram,
The side of the inner square = Distance between the points (0,b) and (a-b,0)
Thus the area of the inner square = (side)²
Now, the side of the outer square = Distance between the points (0,0) and (a,0),
Thus, the area of the outer square = (side)²
Hence, the ratio of the area of the inner square to the area of the outer square
