4 0

Answer:

-5x² +6x

Explanation:

The given expression is :

-3x(x-4)-2x(x+3)

It can be done as follows :

-3x(x-4)-2x(x+3) = (-3x)(x)-(-3x)(4) - 2x(x)-2x(3)

= -3x² +12x -2x² -6x

= -3x²-2x² +12x-6x

= -5x² +6x

Hence, the equivalent expression is equal to -5x² +6x.

How many square inches will it take to cover the outside of the triangular pyramid below? 12 in 10.4 in and 12 in
egoroff_w [7]

Answer:

249.6 sq. in.

Explanation:

In this question, we need to find the surface area of the triangular pyramid in order to calculate how many square inches are needed to cover it. The formula for the surface area of a triangular pyramid is the following

\frac{1}{2}(a × b) + \frac{3}{2}(b × s)

We can say that the values provided represent the following variables.

a = 12in

b = 10.4in

s = 12in

\frac{1}{2}(12 × 10.4) + \frac{3}{2}(10.4 × 12)

\frac{1}{2}(124.8) + \frac{3}{2}(124.8)

62.4 + 187.2

249.6 sq. in.

Finally, we can say that it would take 249.6 sq. in. in order to cover the triangular pyramid.

1. Susan is a space scientist who made this diagram of the Moon and Earth, as seen from above (top view), with sunlight coming f
Sophie [7]

Answer:

d . Because Susan’s diagram is showing that the half of the Moon that is facing the sun is lit by the sun, and the other half is dark

Explanation:

We can see on the diagram on the left side arrows that show the way from which sunlight appears.<u> It only lights up the left side of the sun, while the right one stays dark.</u>

<u>The moon does not produce any light or energy on its own, so only the side that is facing the Sun at the moment is lit up. </u>That is also the only side we can see from the Earth.

Because of the way and pace Earth and moon move through space and around their own axis, we can only constantly see only one side of the moon. The other side always stays dark, and it is often called the “far side of the moon”.

The position of the sun and moon also determine the phases of the moon we see from the Earth. If more of the moon is visible, that means the moon is positioned to directly face the sun and be lit up. If we don’t see much, the sun lights up only that portion of the moon.
