Answer: (x + 4)(x + 2)
Step-by-step explanation: In this problem, we're given a trinomial with an x² term, an x term, and a constant term so we can factor it as the product of two binomials.
The first term in each binomial will be a factor of x² and since x² factors as x time x, we use x as the first term in each binomial.
To fill the second position in each binomial, we use the factors of the last term that add together to equal the coefficient of the middle term.
So we're looking for factors of +8 that add to +6.
+8 factors as 8 x 1 or 4 x 2. Since 4 and 2 add together to equal +6, we put a +4 in our first binomial and a +2 in our second binomial and we have our answer (x + 4)(x + 2) which is a factored version of x² + 6x + 8.
The answer you are looking for is (1, -8)
remember that: x=[(-b/2a)]
and that the problem is set up as y=ax^2+bx+c
calculate:
x=[-8/2(-4)]
x=[-8/-8]
x=1
then:
y=(-4)*1^2+(8*1)-12
y=(-4)+8-12
y=(-4)+8-12
y=4-12
y=(-8)
(1, -8)
Answer:
In one hour, he can code 4/5, 80%, of the game.
Step-by-step explanation:
If he can code 3/5 of his game in 3/4 hour, 60% in 45 minutes, he can code 20% every 15 minutes.
Answer:
8.3838384e+33
Step-by-step explanation:
283838383838382828 + 8383838388828299383838383838288888 = 8.3838384e+33
Answer:
The length of each of the 4 sides of a square is the same. Then
5x - 8 = 3x
2x = 8
x = 4
5(4) - 8 = 12
3(4) = 12
The length of each side is
L = 4.
The perimeter is 4 times the length.
P = 4L = 4(4) = 16
