Answer:
c) FJ and GH
Step-by-step explanation:
Answer:
3x^4 - 13x^3 - x^2 - 11x + 6.
Step-by-step explanation:
x^2-5x+2 x 3x^2 +2x +3
= x^2(3x^2 +2x +3) - 5x(3x^2 +2x +3) + 2(3x^2 +2x +3)
= 3x^4 + 2x^3 + 3x^2 - 15x^3 - 10x^2 - 15x + 6x^2 + 4x + 6
Adding like terms:
= 3x^4 - 13x^3 - x^2 - 11x + 6.
The answer is 32. all you have to do is plug in the numbers for what the letters say they indicate so r=4 so you would plug in 4 where the r is and then plus 6 where the b is and then because b and d are right next to each other, that means you need to multiply so plug in 5 for d and then multiply those together, your equation should end up looking like this
√4 + 6(5)
(0.1x + 0.4y)^2 =
(0.1x + 0.4y)(0.1x + 0.4y)
FOIL method
F (first)...multiply the first terms in each set....0.1x * 0.1x = 0.01x^2
O (outside)...multiply outside terms in each set...0.1x * 0.4y = 0.04xy
I (inside)...multiply inside terms in each set....0.4y * 0.1x = 0.04xy
L (last)...multiply last terms in each set...0.4y * 0.4y = 0.16y^2
now we have : 0.01x^2 + 0.04xy + 0.04xy + 0.16y^2....combine like terms
0.01x^2 + 0.08xy + 0.16y^2 <===
Answer:
21 gallons
Step-by-step explanation:
We can write a ratio
15 gallons x gallons
----------------- = ------------
5 fields 7 fields
Using cross products
15*7 = 5x
Divide each side by 5
15/5 *7 = 5x/5
3*7 =x
21
He will need 21 gallons
