Answer:
Volume of a rectangular prism is 15.75 in.³ the base has an area 10.5 in.²
We also have:
Volume of a rectangular prism (V) = base area x height
=> height = V/base area = 15.75/10.5 = 1.5 in
Hope this helps!

Answer:
(f*g)(x) = 3x³+12x²-7x-28
Step-by-step explanation:
What (f*g)(x) means is that we multiply f(x) by g(x):
f(x) = x+4
g(x) = 3x²-7
(f*g)(x) = f(x)*g(x) = (x+4)(3x²-7) = (x)(3x²)+(x)(-7)+(4)(3x²)+(4)(-7) = 3x³-7x+12x²-28 = 3x³+12x²-7x-28
Answer:
200
Step-by-step explanation:
basically, all you have to do is plug in 30 for n. You would get -3 + 7(30-1), and then you would get -3 + 7 x 29, and then you would get -3 + 203, and the final answer would be 200

Answer:
A = 21
Step-by-step explanation:
Hello
The triangle area is= (base*height)/2, so
A = (6*7)/2
A = 42/2
A = 21
Remember that a trinagle is the area of half square =D
