Area of smaller parallelogram = 15 ft?
Answers
Answer:
135ft^2
Step-by-step explanation:
Area of the smaller parallelogram = Base * Height
15 = 3 * height
Height = 15/3
Height = 5ft
Since they are both similar
Height of the big parallelogram = 3(5) = 15ft
Area of the other parallelogram = 9 * 15
Area of the other parallelogram = 135ft^2

1) What is the product of (3x + 2) and (x - 7)?
2) What are the factors (multiplier) of 3x2 − 9x ?
Answer both of the questions
Answers
Answer:
1) [tex]3x^{2}[/tex]-19x-14
2) x=0, x=3
Step-by-step explanation:
1) (3x+2)(x-7)
Distribute the 3x to both x and -7, as well as the 2 to both x and - 7.
[tex]3x^{2}[/tex] - 21x + 2x -14
Combine like terms
[tex]3x^{2}[/tex] - 19x - 14
2)
In order to find the factors of x, set the expression equal to 0.
[tex]3x^{2}[/tex] - 9x = 0
Factor out the highest common multiple (3x)
3x(x-3) = 0
In order for x to satisfy the equality, you must either have a 0 in the parenthesis -> (x-3)=0 -> x =3
Or 3x = 0 -> x = 0

V = 408 SA = 378
Step-by-step explanation:
To find the volume, you need to first find out the area and multiply it by overall length.
A = 1/2 (6)(8)
= 24
Volume = 24 x 17
= 408
Surface Area
SA = Front and Back + Right Side + Left Side + Bottom
= 2 [1/2 (6) (8)] + (17 x 10) + (3 x 8) + (17 x 8)
= 2 (24) + 170 + 24 + 136
= 48 + 170 + 24 + 136
= 378
