2. So for this question, you do the distributive property, which is multiplying the term outside of the parenthesis by the terms in the parenthesis. In this case, the outside term is 1/2. 8x * 1/2 = 4x and 1/2 * -16 is -8. That brings us to 4x - 8, which is our answer. Therefore, the correct answer choice is B.

3. Okay. In this problem, we are talking about the sum of 12 and a number. That's 12 + n, because sum means the answer to the addition problem D is out, because we don't do distributive property in this case. The sum of 12 + n is 4n. The expression is 12 + n = 4n. The answer is B.

NUMBER 4 DO ANYONE KNOW IT PLEASE HELP
ss7ja [257]

Answer:

The Height of the cliff is 41.5 meters tall.

Option B. 41.5 meters.

Step-by-step explanation:

Given:

AB = 85 meter

Angle of elevation ∠ C= 26°

To Find:

Cliff height = AB = ?

Solution:

In right angle Triangle ABC by tangent Identity we have

\tan C = \frac{\textrm{side opposite to angle C}}{\textrm{side adjacent to angle C}}

Substituting the given values we get

\tan 26 = \frac{AB}{BC}=\frac{AB}{85}

\therefore AB=85\times 0.4877=41.45=41.5\ meters

The Height of the cliff is 41.5 meters tall.

Is the orthocenter of a triangle on the inside ?
likoan [24]

Answer:

It turns out that all three altitudes always intersect at the same point - the so-called orthocenter of the triangle. The orthocenter is not always inside the triangle. If the triangle is obtuse, it will be outside. To make this happen the altitude lines have to be extended so they cross.

1. A soccer field has an area (A = LW) that is represented by the polynomial 1 point
matrenka [14]

Answer:

(x + 6)(x - 6)

Step-by-step explanation:

Given

See attachment for soccer field

Required

The possible dimension of the field

From the attachment, we have:

Area = x^2 - 36

Length = x +a

Width = x + b

So, we have:

Length * Width = Area

This gives:

(x + a)(x + b) = x^2 - 36

Express 36 as 6^2

(x + a)(x + b) = x^2 - 6^2

Express as difference of two squares

(x + a)(x + b) = (x + 6)(x - 6)

Hence, the dimension is: (x + 6)(x - 6)

-75/8 -71/88 which is greater
Setler79 [48]
Trick question. See these negative signs? The left number is -9.375, and the right number is -0.8068181818181818...  Notice that even though the right number looks like a smaller answer, it is closer to 0 on a number line, because it is negative. -71/88 is the correct answer.

Find the slope of the line that passes through the points (-19, -4) and (13, -17).​
Tasya [4]

Answer:

m = \frac{-13}{32}

Step-by-step explanation:

Two point slope formula = \frac{y_{2} - y_{1}  }{x_{2} - x_{1} }

\frac{-17 + 4}{13 + 19} = \frac{-13}{32}
