Using the distributive property simplify the expression<br> -2(5y + 6) + 3 - 5y
vivado [14]

Answer:

\Huge \boxed{-15y-9}

Step-by-step explanation:

To solve this problem, first you have to use the distributive property of \displaystyle a(b+c)=ab+ac.

First, expand.

\displaystyle -2(5y+6)

-2*5=-10

\displaystyle -2*6=-12

\displaystyle -10y-12

\displaystyle -10y-12+3-5y

Next, solve.

\displaystyle -10-12+3-5=\boxed{-15y-9}

In conclusion, the correct answer is -15y-9.

Which rule which allows us to change the sign of an exponent
ruslelena [56]

Answer:

Step-by-step explanation:          

                                                                                       1

Given x³, we can write the equivalent expression -----------

                                                                                    x^(-3)

                                                              1

Given y^(-4) we can rewrite this as  ----------

                                                             y^4

Here we're applying the "rule of negative exponents."

For the upcoming parade, Lauren needed to make her school's triangular flag into a larger, similar triangular flag. Using the in
RoseWind [281]

The ratio of corresponding sides of the triangle are not in the same proportion, hence they are not similar.

<h3>What are similar triangles?</h3>

Two triangles are said to be similar if they have the same shape and angles. Also, the ratio of their corresponding sides are to be in the same proportion.

From the image shown, if the triangles are similar, hence:

AB / DE = AC / DF = BC / EF

Hence:

5.6 / 4 = 4.9 / 3.5 ≠ 2.4 / 1.5

1.4 = 1.4 ≠ 1.6

The ratio of corresponding sides of the triangle are not in the same proportion, hence they are not similar.
