Answer:
What grade is this?
Step-by-step explanation:
B and C because both bases are squares
Answer:
Step-by-step explanation:
<u>Given triangle ACD</u>
- AB = BC
- CD = 2x + 6
- AB = x + 5
- BC = 2x - 3
- P = ?
<u>Perimeter is sum of the side lengths:</u>
AD = CD because D is vertex and the triangle is isosceles
AC = AB + BC because B is midpoint of AC
<u>Then P is:</u>
- P = 2(2x + 6) + (x + 5) + (2x -3) = 4x + 12 + x + 5 + 2x - 3 = 7x + 14
<u>Find the value of x from the AB = BC:</u>
- x + 5 = 2x - 3
- 2x - x = 5 + 3
- x = 8
<u>Then find the value of P:</u>
- P = 7*8 + 14 = 56 + 14 = 70 units
Answer:
300 in.³
Step-by-step explanation:
We find the volume of 1 prism and multiply it by 2.
V = BH
where V = volume of prism, B = area of the base of the prism, H = height of the prism
V = ½bh × H
V = ½(5 in.)(6 in.) × 10 in.
V = 150 in.³
That is the volume of one triangular prism. Now we multiply it by 2.
volume = 2 × 150 in.³ = 300 in.³
