Pretty sure it is A. x4+10x2+48
Because:
If you multiply x^2 by X^2= x4
if you multiply 5^x by 2^x- 5*2=10 and x*x= x2 so it makes 10x2
and then 8*6=46
so if you put that all together then it is x4+10x2+48
Answer:
40
Step-by-step explanation:
3x^2 + 8x = 2
3x^2 + 8x - 2 = 0
D = b^2+4ac
D = 8^2+4(3)(-2)
D = 64+(-24)
D = 64-24
D = 40
Answer:
555
Step-by-step explanation:
(357+452+589+602+775)/5
Answer:
A) 92 shirts
B) y= (38-15)4
Step-by-step explanation:
A) If Alice folds 20 shirts in 5 minute that means she folds 4 shirts per minute. If she folds 4 shirts per minute then 38 minutes minus 15 times 4.
3(b+100)= 6b
3b + 300 = 6b
300 = 3b
b = 100
