1. Find the value of x. 55° (4x - 5)° O 26 O

Paha777 [63]

Answer:

Step-by-step explanation:

The sum of angles in a triangle is 180 degrees, use this and set up an equation;

x + ( 4x -5 ) + 55 = 180

Simplify

x + ( 4x - 5 ) + 55 = 180

5x + 50 = 180

Inverse operations;

5x + 50 = 180

-50 - 50

5x = 130

Solve each quadratic equation by factoring with grouping. 5v2 – 18v = -9

djyliett [7]

Answer:

v = 3 , 3/5

Step-by-step explanation:

$5 {v}^{2} - 18v + 9 = 0 \\ 5 {v}^{2} - 3v - 15v + 9 = 0 \\ v(5v - 3) - 3(5v - 3) = 0 \\ (5v - 3)(v - 3) = 0 \\ v = 3 \\ v = \frac{3}{5}$
