8 years old in in 6th GRADE and I'm pretty sure that the answer for this problem is 8 years old
You can solve this 2 ways: plug in all of the options or solve for x.
i going to solve for x.
given: x^2+2x=24 (subtract 24 on both sides to get make it look like x^2+x+1)
x^2+2x-24=0 (now factor x^2+2x-24 out)
<span>x^2+2x-24 --> (x-4)(x+6)
</span>
new equation: <span>(x-4)(x+6)=0 (now make them both equl zero)
new equaions: </span>x-4=0 x+6=0 <span> (now solve for x for both)
x-4=0 x+6=0
x=4 x=-6
your <span>answer is 4 and -6.
if you were not taught how to do what i just did then i can message you how to plug those numbers into </span></span><span> x^2+2x=24 to find the answer.</span>
The Proportion for the 15/11=28/x
let x be the shadow that is cast by the tree.
so x=(11*28)/15
x= 20.533
If the value of x-y is negative, and x and y are both positive.
x and y are positive numbers. To get negative number while subtracting , the value of x should be less than the value of y.
For example, 5 - 9 = -4
x is 5 and y is 9 both are positive. 5 - 9 is -4 that is negative.
5 is less than 9
From this we can conclude that the value of x is less than the value of y.
