Answer:

B. 16.19

Step-by-step explanation:

We have given height to width ratio of two similar rectangles

Hence, we solve using Proportionality

Height a/Width a = Height b/Width b

21/34 = 10/w

Cross Multiply

21 × w = 34 × 10

w = 34 × 10/21

w = 16.19047619

Approximately to decimal places = 16.19

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

Step-by-step explanation:

Step 1: Define

Point (2, 5)

Point (-3, 7)

Step 2: Identify

x₁ = 2, y₁ = 5

x₂ = -3, y₂ = 7

Step 3: Find slope m

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

Substitute in points [Slope Formula]: $\displaystyle m=\frac{7-5}{-3-2}$
[Slope] [Fraction] Subtract: $\displaystyle m=\frac{2}{-5}$
[Slope] [Fraction] Rewrite: $\displaystyle m=\frac{-2}{5}$
