#7:
It means to solve for y.
#8:
We can write:
l = w + 2
Because it says the length is 2 more than the width.
Complex solutions, namely roots with a √(-1) or "i" in it, never come all by their lonesome, because an EVEN root like the square root, can have two roots that will yield the same radicand.
a good example for that will be √(4), well, (2)(2) is 4, so 2 is a root, but (-2)(-2) is also 4, therefore -2 is also a root, so you'd always get a pair of valid roots from an even root, like 2 or 4 or 6 and so on.
therefore, complex solutions or roots are never by their lonesome, their sister the conjugate is always with them, so if there's a root a + bi, her sister a - bi is also coming along too.
if complex solutions come in pairs, well, clearly a cubic equation can't yield 3 only.
4 times (*) the sum of (+) 14 and 26
4(14 + 16)

D. And trapezoid is not a quadrilateral.
Answer:
or
Step-by-step explanation:
we know that
One astronomical unit is about 93,000,000 miles
so
using proportion
Find out how many astronomical unit represent 20,000 miles
Let
x ----> the number of astronomical unit
simplify
