CD is called the middle base and is equal to :(AB + EF)/2
CD = <span>(AB + EF)/2
4x = [(x</span>²+10) + (8-x)]/2
8x = x²+10+8-x
8x= x²-x+18
x²-9x+18 = 0
x' = [-b+√(b²-4.a.c)]/2a & x" = [-b-√(b<span>²-4.a.c)]/2a
x'= 6 and x" = 3, So we have2 values of x</span>
Yes because you are multiplying 3 z’s and also 3z’s
Answer:
15
Step-by-step explanation:
since 3d is multiplying, it would be set up as 3*5=15
Answer:
y = -x + 4
