Sure, what are the questions?
Answer:
$2.59 per pound of bark.
Step-by-step explanation:
Convert 3 tons to pound
1 ton = 2,000 pounds.
3 x 2,000 = 6,000
Now divide the $ and the pounds to find the $ per pound rate
6,000 ÷ 15,540 = 2.59
$2.59
4(73)+3
273+3
276
Because you have to subsititue 73 for x. So you have to multiply 73 by 4 then what you get out of that you have to add it by 3.
26,345,000
2.6345 * 10^7
2.6345 e7
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
