Elanso [62]

(2x^2 + 7x - 5) + (-8x^2 - 3x + 5)

= -6x^2 + 4x

That is the answer, but if you need to factor it further:

= 2x(-3x + 2)

O is the center of the circle. Assume that lines that appear to be tangent are tangent. What is the value of x?

brilliants [131]

Answer:

$\boxed{\boxed{x^{\circ}=78^{\circ}}}$

Step-by-step explanation:

Given that, O is the center of the circle and PQ is a tangent to the circle at point Q. OQ is a radius of the circle.

We know that, a tangent to a circle is a line which just touches the circle. And the angle between the tangent and radius is 90°.

Hence, ΔOQP is a right angle triangle. We know that the sum of the measurements of all the 3 angles of a triangle leads to 180°. So,

$\Rightarrow m\angle O+m\angle Q+m\angle P=180^{\circ}$

$\Rightarrow x^{\circ}+90^{\circ}+12^{\circ}=180^{\circ}$

$\Rightarrow x^{\circ}=180^{\circ}-90^{\circ}-12^{\circ}=78^{\circ}$

Trava [24]

In here, we could write an equality as x – 12 < 65. In solving inequalities, we follow the same rule as solving algebraic expressions. We will transpose 12 to the other side, giving us x < 65 + 12. Simplifying, we have x < 77. Geraldo must have a bill less than $77 in order for him not to spend more than $65.
