Solve x^2 − 4x = 14.
DENIUS [597]
Minus 14 from both sides
x²-4x-14=0
use quadratic formula because we cant factor

for
ax²+bx+c=0
x= \frac{-b+/- \sqrt{b^2-4ac} }{2a}

so
1x²-4x-14=0
a=1
b=-4
c=-14

x= \frac{-(-4)+/- \sqrt{(-4)^2-4(1)(-14)} }{2(1)}
x= \frac{4+/- \sqrt{16+56} }{2}
x= \frac{4+/- \sqrt{72} }{2}
x= \frac{4+/- 6\sqrt{2} }{2}
x= 2+/- 3\sqrt{2}

the solutions are
x=2+√3 and
x=2-√3

Triangle RST has sides measuring 22 inches and 13 inches and a perimeter of 50 inches. What is the area of triangle RST? Round t
VladimirAG [237]

Using the Heron's formula, the area of the triangle is: D. 95 square inches.

<h3>What is the Heron's Formula?</h3>

Area = √[s(s - a)(s - b)(s - c)] where s is half the perimeter, or (a + b + c)/2.

Given the following:

s = semi-perimeter = 1/2(50) = 25 in.

a = length of side a = 22 in.

b = length of side b = 13 in.

c = length of side c = 50 - 22 - 13 = 15 in.

Plug in the values

Area = √[25(25 - 22)(25 - 13)(25 - 15)]

Area = √[25(3)(12)(10)]

Area ≈ 95 square inches.
