3 launchers + shipping = $50
shipping = $5
so to find the price of just the launchers we do $50-$5=$45
so 3 ballons = $45
divide be 3 to find the price of one launcher $50 / 3 = $15
Answer:
Answer:
A) The volume of figure 1 is 45 cm³ greater than the volume of figure 2
Step-by-step explanation:
Let's start by calculating the volumes of both figures
Figure 1
Rectangular prism
V = Bh
V = (15*6)(5)
V = (90)(5)
V = 450 cm³
Triangular prism
V = Bh
V = 1/2(3*15)(6)
V = 1/2(45)(6)
V = 1/2(270)
V = 135 cm³
Add them together, you get 585 cm³
Figure 2
Rectangular prism
V = Bh
V = (6*15)(5)
V = (90)(5)
V = 450 cm³
Rectangular pyramid
V = 1/3 Bh
V = 1/3 (15*6)(3)
V = 1/3 (90)(3)
V = 1/3 (270)
V = 90 cm³
Add them together, you get 540 cm³
Subtract 540 from 585 and get 45
I agree. Both of the equations come out to 2x^2+14x+20
(2x+10)(x+2)
Use the FOIL method
2x^2+4x+10x+20
Combine like terms
2x^2+14x+20
(2x+4)(x+5)
Use the FOIL method
2x^2+10x+4x+20
Combine like terms
2x^2+14x+20
I think the answer will be 5?
