Answer:
x = 71/5 (as an improper fraction)
x = 14 1/5 (as a proper fraction
x = 14.2 (as a decimal)
Step-by-step explanation:
It's a rectangle so the diagonals are equal
7x - 9 = 2x + 62
Subtract 2x from both sides
5x - 9 = 62
Add 9 to both sides
5x = 71
Divide both sides by 5
x = 71/5 (as an improper fraction)
x = 14 1/5 (as a proper fraction
x = 14.2 (as a decimal)
The radius of a circle is half the diameter.
Thus, the radius (r) is >>>

The area of a circle is given by the formula,

Where
r is the radius
Substituting the radius value into the area formula, we have:
Answer:
- 12
Step-by-step explanation:
Substitute both the values of x and y in the equation given
x=2, y=4
4(2)-5(4)= 8-20
= - 12
Yea Syd is right it has to be 5 + u
