1. a=h(b+c)
2. distribute the h:
a=hb+hc
3. move the 'hb' to the left:
a - hb = hc
4. subtract the a from both sides:
-hb = hc - a
5. divide both sides by -h to isolate b:
b = -hc+a/h

Answer:
B They are similar, but not congruent.
Step-by-step explanation:
Reflection, rotation, and translation are "rigid" transformations. They result in congruent figures.
Dilation is not a rigid transformation. For any dilation scale factor other than 1, the figures will be different sizes, so will not be congruent. They will be similar. (Angles will be congruent, and lines/sides will be parallel.)
The combination of dilation (by 0.5) and reflection results in similar, but not congruent, figures.

1 because It's a whole question and when divided u get one
Answer: 275 + 
+20.2 = 296
275 + - 20. = 255.
Step-by-step explanation:
275 + + 20.2 (
= 275 + 0.8 + 20.2
= 275.8 + 20.2 = 296
275 + - 20.2
= 5 + 0.8 - 20.2 ( = 0.8)
= 275.8 - 20.2 = 255.
I hope this answer your
Altitude = sqrt [(4sqrt5)^2 - 862 = 4 ft
Perimeter of the trapezoid = 8+4+16+4sqrt5 = 28+4sqrt5
= 36.94 feet to nearest hundredth answer
Area = 1/2 * 4 * (8+16) = 48 ft^2 answer
