Answer:
length = 10 in, width = 6 in
Step-by-step explanation:
Let the width be x.
Then, length = (x+4)
Area = 60 in²
Area of a rectangle = width × length
60 = x × (x+4)
60 = x² + 4x
x² + 4x - 60 = 0
Splitting the middle term :-
x² + 10x - 6x - 60 = 0
x (x + 10) - 6 ( x + 10) =0
(x + 10) ( x - 6)
x = -10 (doesn't fulfill our requirement)
x = 6
So, width = 6 in
length = 6+4 = 10 in
Answer:
Step-by-step explanation:
1. Create an equation
<em><u>Concept</u></em> :
If x = 5, then subtracting 5 from both sides gives you x - 5 = 0. Do this to both variables
If x - 5 = 0 and y - 12 = 0, those two statements equal the same thing. So
2. Add 5 to both sides to isolate variable X
3. (Optional) Plug given values into new equation to check answers
5 = 5 is a true statement
It would be multiplication and subtraction
4(x-3)
four times
( the difference of a number “x” and three)
difference means subtraction every time.
I think the answer is 2 because you can fit one whole and there are two halves too
46 degrees as the angle is between R and T
