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>
26-22x is the correct answer
Answer:
<h3>1952.00</h3><h3>I=976</h3>
Step-by-step explanation:
<u><em>SIMPLE INTEREST FORMULA:</em></u>
I- Interest
P- Principal
R- Rate
T-Time
P=976
R=25
T=4 years
976*25%4
25%=0.25
Solve.
Multiply.
976*0.25*4
976*0.25*4=976
I=976
976 and $1952.00, which is our answer.
Answer:
a=2.5
Step-by-step explanation:
3a-2.4=5.1 Add the like terms ( plus 2.4 cancels out -2.4)
+2.4 +2.4
3a=7.5 Now divide by 3
/3 /3
a=2.5
5n =70
5 x 14 = 70
hope this helped :)
