Answer:
(x-8)(x^2-2)
Step-by-step explanation:
take x common from the first 2 terms and take -2 common from the last two terms. Then, take (x-8) common.
x^2(x-8)-2(x-8) = (x-8)(x^2-2)
Let's say that y is the weight of the mother and x is the weight of the baby.
We know that the baby is 7437 pounds less than the mother, which means you need to add 7437 pounds to the baby's weight to get the mother's.
We can show it like this:
x+7437=y.
We know what the baby's weight is (1400 lbs), so just sub it in:
1400+7437=y
y=8837 lbs
The mom weighs 8837 pounds.
Answer: 29.41 pounds
Step-by-step explanation:
You have the following information given in the problem:
- The fat percentage that the person has is 17.2%
- The person weighs 171 pounds.
Therefore, to calculate the amount of pounds of her weight is made up of fat (which you can call x), you must multiply the weight of the person by the fat percentage.
Therefore, you obtain the following result:
Firstly, divide 30 by 1425
Then, 1425/30 = 47.5
A Mixed number = A whole number + fraction
Your final answer = 47 1/2 trains
Hope this helps <3 Good luck with future exams!
P.S Fun Fact~~ The Mona Lisa has no eyebrows!
Let the width be x, the length is then 3x-10
Area of a rectangle is length times width: x(3x-10)=77 => 3x^2-10x-77=0
Factor this quadratic equation: (x-7)(3x+11)=0 =.x=7 or x=-11/3
width cannot be negative, so the only answer is x=7
width is 7m, length is 11m
