To do this you would have to use the Pythagorean Theorem, which is
a^2+b^2=c^2
The longest side would be your c^2, the smallest side is your a^2, and the remaining side is your b^2
The 7 is your a^2, 24 is b^2, and x is c^2
Plug in the numbers into your equation
7^2+24^2=x^2
Then, just solve:
49+576=x^2
625=x^2
To get rid of the ^2 in x^2, you would have to square root both sides to get x by itself
25=x
So x is equal to 25
Hope this helps!
It's -5.25 because 5*8 is 40 and 6*8 is 48.
replace x^2 with m and try to solve
-3 m^2 +27 m +1200 =0
factor out -3
-3(m^2 -9m-400)=0
-3 (m-25) (m+16) =0
using the zero product property
m-25 =0 m+16=0
m=25 m=-16
then substitute m=x^2 back in
x^2 = 25 x^2 = -16
x take the square root of each side
x = +- sqrt (25) if you know complex number x = +- sqrt (-16)
x = +-5 x = +- 4i
Answer: +5, -5 , +4i, -4i
Answer:
$16
Step-by-step explanation:
if 5=20 then 20÷5=4 and 4x4=16
