To find the volume, you just have to multiply length × width × height. The length is usually the long side, the width is usually at the side, and the height goes up and down. Hope this helped ☺
Answer:
Yes
Step-by-step explanation:
Rectangle 1 dimensions are 12 feet by 16.5 feet
Rectangle 2 has dimensions of 8 inches by 11
inches.
Checking the scale WITHOUT CONVERTING units
12/8=1.5
16.5/11=1.5
Since both have a factor of 1.5, it means the two rectangles are the same but on different scales. However, in case the scale would not have been the same, we would have concluded otherwise. Therefore, triangle 1 is enlargement of triangle 2. These are similar rectangles with different scales.
Step-by-step explanation:
Simplifying
(7a + 3b)(7a + -3b) = 0
Multiply (7a + 3b) * (7a + -3b)
(7a * (7a + -3b) + 3b * (7a + -3b)) = 0
((7a * 7a + -3b * 7a) + 3b * (7a + -3b)) = 0
Reorder the terms:
((-21ab + 49a2) + 3b * (7a + -3b)) = 0
((-21ab + 49a2) + 3b * (7a + -3b)) = 0
(-21ab + 49a2 + (7a * 3b + -3b * 3b)) = 0
(-21ab + 49a2 + (21ab + -9b2)) = 0
Reorder the terms:
(-21ab + 21ab + 49a2 + -9b2) = 0
Combine like terms: -21ab + 21ab = 0
(0 + 49a2 + -9b2) = 0
(49a2 + -9b2) = 0
Solving
49a2 + -9b2 = 0
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '9b2' to each side of the equation.
49a2 + -9b2 + 9b2 = 0 + 9b2
Combine like terms: -9b2 + 9b2 = 0
49a2 + 0 = 0 + 9b2
49a2 = 0 + 9b2
Remove the zero:
49a2 = 9b2
Divide each side by '49'.
a2 = 0.1836734694b2
Simplifying
a2 = 0.1836734694b2
take the square root of each side:
a = {-0.428571429b, 0.428571429b}
It would be 25 how I got that answer was I did 200 ÷ 8 and that gave me 25
