Picture relating to the question can be found in the picture attached below.

Answer:

Angle DCA = Angle CAB

Angle A + Angle B + Angle C = 180°

18 + 3x + 3x = 180

27°

Step-by-step explanation:

For 1:

Angle DCA = Angle CAB (Alternate angles are equal)

Angle DCA = 18°, Hence, CAB = 18°

Angle A + Angle B + Angle C = 180° (sum of interior angles in a triangle)

3.)

Angle A = 18°

Angle B = 3x

Angle C = 3x

18° + 3x + 3x = 180°

4.)

18 + 3x + 3x = 180

18 + 6x = 180

6x = 180 - 18

6x = 162

x = 162 / 6

x = 27°

The amount of arable land in the US in the year 2000 was 20% of total land area. Currently, the amount of arable land in the US

Slav-nsk [51]

The percent change in arable land area in the US over this time period is 12.5%

<h3>Percentage Change</h3>

From the question, we are to determine the percent change in arable land area over the given time

Let the total land area be x

From the given information,

In the year 2000, the amount of arable was 20% of total land area

That is,

Amount of arable land = 20% of x

Amount of arable land = 0.2 × x

Amount of arable land = 0.2x

Currently,

The amount of arable land is 17.5% of total land area

Amount of arable land = 17.5% of x

Amount of arable land = 0.175 × x

Amount of arable land = 0.175x

Thus,

Percent change = (0.2x - 0.175x)/0.2x × 100%

Percent change = 0.025x/0.2x × 100%

Percent change = 0.125 × 100%

Percent change = 12.5%

Hence, the percent change in arable land area in the US over this time period is 12.5%

(7y^3 - 3y) + (8y^2 - 8y) help combine like terms

defon

Like terms are terms that are the exact same excluding the coefficient.
The answer here would be 7y^3+8y^2-11y
The only like terms here are y. y^3 and y^2 aren't the same because they have different exponents
