Answer:

\frac{5}{3}

Step-by-step explanation:

Given that the triangles are similar then the ratios of corresponding sides are equal.

To determine the scale factor calculate the ratio of corresponding sides, that is

\frac{NO}{GH} = \frac{15}{9} = \frac{5}{3}

Which is an equation of the line with a slope of (1,4) and a y-intercept of-2​
anzhelika [568]

Answer:

y=6x-2

Step-by-step explanation:

Fisrt things first, you want to find the slop. One of the points is (1,4). You want the other point. Using the y-int, you can figure out the other point is (0,-2). You get this because the y-intercept means the x value is 0.

Next you use the two points and plug it into the formula (change in y/ change in x)

(-2-4)/(0-1)=-6/-1 = 6

Now you know the slope is 6. Since you know the y-int, you can plug that into the slope-intercept formula (y=mx+b)

That would give you: y=6x-2

A rectangle has sides measuring (2x + 7) units and (5x + 9) units. Part A: What is the expression that represents the area of th
andrey2020 [161]

Answer:

Part A:  

(2x+7)(5x+9)

=(2x+7)(5x+9)

=(2x)(5x)+(2x)(9)+(7)(5x)+(7)(9)

=10x2+18x+35x+63

=10x2+53x+63

A)

The formula for determining the area of a rectangle is given as

Area = length × width

Given that the length and width are (2x + 6) units and (5x + 3) units, the expression for the area is

(2x + 6)(5x + 3) = 10x² + 6x + 30x + 18

Area = 10x² + 36x + 18

B)

The degree is 2 because the highest power of the terms is 2. It is classified as a trinomial because it has 3 terms.

C) it is closed under multiplication. the exponents in the polynomials are whole numbers(2 and 1). The whole numbers are closed under addition, which means that the new exponents formed are also whole numbers. The exponents were whole numbers before multiplication and doesn't change after multiplication.
