Solve for x. Assume that lines which appear tangent are tangent.

NeX [460]

Answer:

x=2

Step-by-step explanation:

The angle formed by two tangents intersecting outside of a circle is half the difference of the intercepted arcs.

This implies that:

$55=\frac{1}{2}(116x+3-(180-55))$

We need to simplify this ad solve for x to get:

$110=(116x+3-125)$

Group the similar terms to get:

$110-3+125=116x$

232=116x

Divide by 116 to get:

x=2

How much larger would the volume of a prism be if it was increased by a scale factor of 5

jek_recluse [69]

We know that

if the volume of a prism <span>it was increased by a scale factor of 5
then
</span>the original volume is multiplied by 5*5*5-------> 5³=125

therefore
the new volume compared with the original is 125 times larger

Answer:

see below and attached

Step-by-step explanation:

To solve a system of quadratic equations:

Equal the equations then rearrange so that it is set to zero.
Use the quadratic formula to solve.

I have done this (see attached workings) but cannot get any of the solutions you've provided. I have even graphed the two functions, and the points of intersection concur with my workings (see attached graph).
