Answer:
68 in.
Step-by-step explanation:
The rectangle is 60in., and you can find the area of a triangle by multiplying the height and the width, then dividing it by 2. The height is four, and the width is 4, 4x4 is 16, divided by 2 is 8.
Answer:
The answer is 9x-4/(x+2)(x-2)
Answer:
5 feet
Step-by-step explanation:
Add 0.25 to both sides of the equation:
4.75 +0.25 = x - 0.25 +0.25
5.00 = x
The original height of the water in the pool was 5.00 feet.
Answer:
(-9+√17)/8
Step-by-step explanation:
its an example of quadratic
Answer:
4.8
Step-by-step explanation:
JK is twice as long as LM, so is 4.8 units long.
"Similar" means the sides of one figure have the same ratio as the corresponding sides of the other figure. We see that AB = 2×CD. JK corresponds to AB, and LM corresponds to CD.
__
We could bother to calculate that sides of JKLM are 1.2 times as long as the corresponding sides of ABCD, but that is not necessary. We only need to find a convenient ratio between the side we want and some other known side. I like a ratio of 2, because it is easy to double a number. We find AB=2CD, so JK=2LM=2×2.4 = 4.8.
