6 0

7x^{2} +33x-10=0

\implies 7x^{2} +35x-2x-10=0\\\implies7x(x+5)-2(x+5)=0\\\implies (7x-2)(x+5)=0

7x - 2 = 0\\\implies \boxed{\bold{x = \frac{2}{7} }}

x+5=0\\\implies \boxed{\bold{x=-5}}

The shape goes through three transformations, and turns 180 degrees in total (flips). Therefore, each transformation is 180/3=60 degrees. The vertical of the L turns left in the first transformation, so that means that the L turns counterclockwise. The answer is 60 degrees counterclockwise.

When would you use the total 180° to find the measure of an angle?
Rufina [12.5K]

Answer:

In any instance.

Step-by-step explanation:

A triangle has three sides, and the angle measures for all three angles will add up to a total of 180°.

∠A + ∠B + ∠C = 180°

<u><em>Example:</em></u>

Find ∠C if ∠A = 60° and ∠B = 50°.

60° + 50° +∠C = 180°

∠C = 70°

Determine whether the piece of paper can be used to wrap the rectangular prism exactly once without any gaps or overlaps.
liq [111]

Answer:

No, because they do not have the same area.

Step-by-step explanation:

For the piece of paper to cover once without overlap or gaps, it must have the same area as the the total surface area of the prism.

The total surface area of the rectangular prism is: 2(3.5\times2+3.5\times1.5+2\times1.5)=30\frac{1}{2}in^2

The area of the rectangular sheet is:5\times 8=40in^2

Since the area of the piece of paper is more than the surface area of the rectangular prism there will be an overlap.
