Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point (-1, 0)

Point (0, 1)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [SF]: $\displaystyle m=\frac{1-0}{0--1}$
[Fraction] Simplify: $\displaystyle m=\frac{1-0}{0+1}$
[Fraction] Subtract/Add: $\displaystyle m=\frac{1}{1}$
[Fraction] Divide: $\displaystyle m=1$

Find the surface area of the rectangular prism. 2 cm 6 cm 3 cm 3 cm

Nookie1986 [14]

Answer:

72. If the second 3cm has some relevance, leave a note and I'll come back and modify my answer.

Step-by-step explanation:

Givens

L = 6 cm

W = 3 cm

H = 2 cm

I don't know what the extra 3 cm is for.

Formula

SA = 2*L*W + 2*L*H + 2*H*W

SA = 2*6*3 + 2*6*2 + 2*2*3

SA = 36 + 24 + 12

SA = 72
