Answer:

A ≈ 5.6

Step-by-step explanation:

The area (A) of the triangle is calculated as

A = $\frac{1}{2}$ × PQ × PR × sin P

= 0.5 × 5.2 × 2.8 × sin50°

≈ 5.6 ( to 1 dec. place )

Use the quadratic formula to solve the equation.

Sergeeva-Olga [200]

ANSWER

$x = \frac{ 5 - \sqrt{ 5} }{4} \: or \: \: x = \frac{ 5 + \sqrt{ 5} }{4}$

EXPLANATION

The given quadratic equation is

$4 {x}^{2} - 10x + 5 = 0$

We compare this to

$a {x}^{2} + bx + c = 0$

to get a=4, b=-10, and c=5.

The quadratic formula is given by

$x = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac} }{2a}$

We substitute these values into the formula to get:

$x = \frac{ - - 10 \pm \sqrt{ {( - 10)}^{2} - 4(4)(5)} }{2(4)}$

This implies that

$x = \frac{ 10 \pm \sqrt{ 100 - 80} }{8}$

$x = \frac{ 10 \pm \sqrt{ 20} }{8}$

$x = \frac{ 10 \pm2 \sqrt{ 5} }{8}$

$x = \frac{ 5 \pm \sqrt{ 5} }{4}$

The solutions are:

$x = \frac{ 5 - \sqrt{ 5} }{4} \: or \: \: x = \frac{ 5 + \sqrt{ 5} }{4}$
