An right angle has a 90 degree angle , plus it's acute right triangle so it's degrees are 30-60-90 . So to find the hypotenuse you multiply the short leg by two . So your hypotenuse is 6

How can I find the complex roots of 125x^3+343. Please explain your steps

8_murik_8 [283]

First we assume that this is equal to zero

so what we notice is this is a sum of 2 perfect cube

recall that
a^3+b^3=(a+b)(a^2-ab+b^2)

125x^3+343=
(5x)³+(7)³=(5x+7)(25x²-35x+49)

now solve the part in second parenthasees because we can see that the first parenthasees (5x+7) is going to have a real root

remember quadratic formula

for ax^2+bx+c=0
x= $\frac{-b+/- \sqrt{b^2-4ac} }{2a}$
a=25
b=-35
c=49

x= $\frac{-(-35)+/- \sqrt{(-35)^2-4(25)(49)} }{2(25)}$
x= $\frac{35+/- \sqrt{1225-4900} }{50}$
x= $\frac{35+/- \sqrt{-3675} }{50}$
x= $\frac{35+/- (\sqrt{3675})( \sqrt{-1}) }{50}$
x= $\frac{35+/- (\sqrt{3675})(i) }{50}$
x= $\frac{35+/- 35i\sqrt{3} }{50}$
x= $\frac{7+/- 7i\sqrt{3} }{10}$

the comlex roots are

x= $\frac{7+ 7i\sqrt{3} }{10}$ and $\frac{7- 7i\sqrt{3} }{10}$

The area of a rectangular picture frame is 30 1/3 square inches. The length of the frame is 6 1/2 inches. Find the width of the

likoan [24]

Area of a rectangle= l·w

(30 1/3)/6.5=(6.5w)/6.5

14/3=w

w= 14/3 or 4 2/3 inches

Find the absolute value<br><br> l-7.5l

Hoochie [10]

An absolute value is "how far a number is from zero."

When there's a negative number, all you do is take out the negative sign and think of it as a positive number. Therefore, the absolute value is 7.5.
