First find half of the perimeter of the triangle: s = (a + b + c) / 2 = 11.095

Then the area is:

A = Square Root [11.095 (11.095 - 7.7)(11.095 - 5.2)(11.095 - 9.29)] = 20.01999895 or 20.02 square feet rounded to 2 decimal places.

Solve 11 2/5 = q - 4 2/7 + 2 1/7
RideAnS [48]
I turn the mixed numbers into decimals before doing anything else.
11 2/5----> 57/5----> 11.4
4 2/7----> 30/7----> 4.29
2 1/7----> 15/7----> 2.14

11.4=q-4.29+2.14
11.4=q-2.15
13.55= q

13.55 converted to a fraction is 13 11⁄20
q=13 11⁄20

Find two consecutive even integers such that the square of the second, decreased by twice the first is 52
Fiesta28 [93]

Let the first integer be x. So, the next even number is x+2

Let's translate the formula: the square of the second is (x+2)^2, twice the first is 2x. So, the equation is

(x+2)^2 - 2x = 52

Expand the square to get

x^2+4x+4-2x = 52 \iff x^2+2x+4 = 52 \iff x^2+2x - 48 = 0

The solutions to this equations are

x = -8,\quad x = 6

So, the possible consecutive even numbers are

-8\text{ and } -6\quad\text{or}\quad 6\text{ and } 8
