2 1/2 because you divide the 15 by 6 and 2 R.3 3 is half of 6 so you make it a half leaving you with 2.5 or fraction form:2 1/2
Answer:
(a - 2) • (3a - 4)
Step-by-step explanation:
(3a2 - 10a) + 8
Trying to factor by splitting the middle term
2.1 Factoring 3a2-10a+8
The first term is, 3a2 its coefficient is 3 .
The middle term is, -10a its coefficient is -10 .
The last term, "the constant", is +8
Multiply the coefficient of the first term by the constant 3 • 8 = 24
Find two factors of 24 whose sum equals the coefficient of the middle term, which is -10 .
-24 + -1 = -25
-12 + -2 = -14
-8 + -3 = -11
-6 + -4 = -10 That's it
Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -6 and -4
3a2 - 6a - 4a - 8
Add up the first 2 terms, pulling out like factors :
3a • (a-2)
Add up the last 2 terms, pulling out common factors :
4 • (a-2)
Add up the four terms of step 4 :
(3a-4) • (a-2)
Which is the desired factorization
Final result :
(a - 2) • (3a - 4)
According to the problem's info, we have:
(1 + 2 + 4)pieces of fabric = 1bug
(7)pieces of fabric<span> = 1bug
</span>so we know for each bug Missy uses 7 pieces of fabric (of different shapes).
Then, if she uses 70 pieces (7*10) of fabric, those are 10 bugs(1*10) built.
so we have to multiply by 10 the amount of pieces used in one bug:
hexagonal = 1*10 = 10
rectangular = 2*10 = 20
triangular = 4*10 = 40
which give us 70 pieces total.
