I don't know the answer because i don't know the question
if you can simplify the question
A
you have to solve x^2+x-5=0
So x=(-1 +/- sqrt(1^2+4*1*5))/2
x=(-1 +/- sqrt(21))/2
Length is l
width is w
l*w = 30
2l + 2w = 34
You can simplify the second equation to l + w = 17
Factors of 30:
30*1
15*2
10*3
6*5
Try adding each of these factors together, to find out which equals 17
30 + 1 = 31
15 + 2 = 17
10 + 3 = 13
6 + 5 = 11
So the dimensions of the rectangle are 15m * 2m
Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees.
In radians this are
To find the complement of 3π/4, subtract it by π/2
To find the supplement of 3π/4, subtract it by π.
