Answer

3.

q + 21

4.

7s - 5t + 8

Step-by-step explanation:

In question #3, you combine the like term terms. In this example, 7q and -6q, as well as +8 and +13. Therefore, when you combine these terms, the solution is q + 21.

In question #4, the same method is used. You simply have to combine the like terms, only this time with another variable. The only terms to combine are: 3s +  4s = 7s. We are left with the following: 7s - 5t + 8.

Hope that helped!!

In you own words what does the term American Dream mean to you?
ira [324]

Answer:

What the American dream means to me is freedom. By freedom I mean everyone has the rights that a American citizen has. But also not having everyone thing be about politics and have everything be about what’s best for the American people, but also a place where no one is judged for what they believe in, but instead have their beliefs glorified. That is what the *American Dream* Means to me.

*-This is all in my on words-*

(Hope this helps)

A bird (B) is spotted flying 6,000 feet from a tower (T)). An observer (O) spots the top of the tower (T) at a distance of 9,000
Flura [38]

Answer:

∅ ≈ 56.31°

Step-by-step explanation:

The bird is spotted flying 6000 ft from a tower . The distance of the tower from the bird is 6000 ft. The height of the tower is 9000 ft because the observer spot the distance from the top of the tower at a distance of 9000 ft.

The illustration forms a right angle triangle. The adjacent side of the triangle is  6000 ft and the height or opposite side of the triangle is 9000 ft. Using tangential ratio the angle of depression from the bird to the observer can be found as follows.

Let

∅ = angle of depression

tan ∅ = opposite/adjacent

tan ∅ = 9000/6000

tan ∅ = 1.5

∅ = tan⁻¹ 1.5

∅ = 56.309932474

∅ ≈ 56.31°

Convert the expression (5x + 2)(x - 7) from factored form to standard form
tensa zangetsu [6.8K]
We use the FOIL method here. First, Outer, Inner, and Last.

(5x)(x) = 5x^2

(5x)(-7) = -35x

(2)(x) = 2x

(2)(-7) = -14

5x^2 - 35x + 2x - 14

Now combine like terms.

5x^2 - 33x - 14.

This is the right answer because it is now in the form of ax^2 + bx + c
