To solve this quadratic, use factoring:
add 5 to both sides
factor this into two binomials using factors 3 and 8 for 24
(x-3)(x-8)=0 for this to be a true statement either the first binomial factor or the second binomial factor must equal '0'..
so x=3 and x=8
A dice has 6 sides. All sides have an equal chance of being rolled. The probability of rolling any number on the dice is 1/6. So you take 96 and find 1/6 of it and you do 96 divides by 6. Your answer is 16. Therefore, Adam is expected to roll a 4, 16 times.
2 parts.....ratio is 5:3...added = 8.....so one of the parts is 5/8 of the total...5/8x....and the other part is 3/8 of the total...3/8x
the difference is 6...
5/8x - 3/8x = 6
2/8x = 6
x = 6 * 8/2
x = 48/2
x = 24
so the total length is 24
with the longest being : 5/8(24) = 15 <==
and the shortest being : 3/8(24) = 9

+4ab+5b
2
Step-by-step explanation:
step 1. (((0-(4•(a2)))+3ab)+(12•(b2)))+(((9•(a2))+ab)-7b2)
step 2. (((0-(4•(a2)))+3ab)+(12•(b2)))+((32a2+ab)-7b2)
step 3.(((0-(4•(a2)))+3ab)+(22•3b2))+(9a2+ab-7b2)
step 4. (((0-(4•(a2)))+3ab)+(22•3b2))+(9a2+ab-7b2)
step 5. 5.1 Factoring 5a2 + 4ab + 5b2
