Answer:

A=27 cm^2

B=24 cm^2

C=26 cm^2

D=28 cm^2

Step-by-step explanation:

Break each problem down into individual shapes.

For instance, A can be split into a 3 by 3 square and a 6 by 3 square.

Get the area by multiplying the length & height: A = L * H

For the triangles the area is the same equation divided by 2 A=LH/2

Shapes with unclear dimensions like C can be skipped and have their area revealed through process of elimination.

Slope formula: $\frac{y_2-y_1}{x_2-x_1}$

Firstly, let's set up our equation. Place the two coordinates in the slope formula and have it equal 8: $\frac{3k-4-k}{5-(-2)}=8$

Next, combine like terms: $\frac{2k-4}{7}=8$

Next, multiply both sides by 7: $2k-4=56$

Next, add 4 onto both sides of the equation: $2k=60$

Lastly, divide both sides by 2 and <u>your answer will be $k=30$ </u>

Allison measured a line to be 5.4 inches long. If the actual length of the line is 5.5 inches, then what was the percent error o

valentina_108 [34]

Answer:

1.85%

Step-by-step explanation:

→ Find the difference between the actual and predicted

5.5 - 5.4 = 0.1

→ Divide answer by 5.4

0.1 ÷ 5.4 = 0.01851851851

→ Multiply answer by 100

0.01851851851 × 100 = 1.85%

Given the sequence 5, -10, 20, -40, the next two numbers in the sequence are 80 and -160. true false

jarptica [38.1K]

It is true because every term is the previous term multiplied by -2. So, -40 x -2 = 80, 80 x -2 = -160
