Answer:
(x +9)(x +8)
Step-by-step explanation:
In a quadratic with leading coefficient 1, the coefficient of the linear term (17) is the sum of factors of the constant term (72). If you know your times tables, you know that 8×9 = 72, and you also know that 8+9 = 17.
With these facts, you can write the factorization as ...
(x +8)(x +9)
_____
If you need to see the working out, rather than jumping to the end, you can use the sum information to rewrite the linear term:
x^2 +(8x +9x) +72
Now factor pairs of terms:
(x^2 +8x) + (9x +72) = x(x +8) +9(x +8) = (x +9)(x +8)
_____
It also helps to be familiar with the product of binomials:
(x +a)(x +b) = x^2 +(a+b)x +ab
Answer:
So, I don't quite have the answer, but I believe you just turn that into an improper fraction and divide it by 8 classes? Decimal Answer.
Step-by-step explanation:
Answer:
48 units sq
Step-by-step explanation:
Find the area of each square/rectangle
2x2
2x5
2x5
2x5
2x2
2x5
Add all the parts together
4 + 10 + 10 + 10 + 4 + 10
= 48 units sq
Answer:
6
Step-by-step explanation:
8(1/4) is 2 bc 1/4 of 8 is 2
2-1=.5(10)
.5 works like 1/2 so 1/2 is 10 is 5
then you get 2-1+5 then after that you get 6
