Determine B pls quickly!

Assuming the two horizontal legs are parallel, the smaller triangle is similar to the larger one, so that corresponding sides occur in a fixed ratio. In particular, you have

(6 cm) / (4 cm) = (6 cm + b) / (7 cm)

Solve for b :

(6 cm) • (7 cm) / (4 cm) = 6 cm + b

b = (6 cm) • (7 cm) / (4 cm) - 6 cm

b = 9/2 cm = 4.5 cm

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.

step-by-step explanation:

c. (3,2,6) is the answer.
