Answer:
(3x +2)(x +1)
Step-by-step explanation:
A number of different ways are suggested for doing this. One that seems straightforward is this.
For ax^2 +bx +c, look for factors of ac that total b. Here we have ...
ac = 3·2 = 6
b = 5
It is easy to see that the factors we just multiplied to get 6 are ones that total 5: 3+2 = 5.
Now, rewrite the "bx" term using this sum.
3x^2 +3x +2x +2
Factor each pair of terms.
3x(x +1) +2(x +1)
And factor out the common factor:
(3x +2)(x +1)
Answer:
Step-by-step explanation:
<u>Given line </u>
<u>Perpendicular lines have negative-reciprocal slopes, so the line will be:</u>
<u>Use the point (3, 1) to find b:</u>
- 1 = -1/3(3) + b
- 1 = -1 + b
- b = 2
<u>The line is:</u>
Answer:
x = 15 in
you can use the Pythagorean Theorem because you know the legs of the triangle and need to find the hypotenuse
the left leg of the triangle is 9 because 9² = 81
the bottom leg of the triangle is 12 because 48/4 = 12
9² + 12² = x²
81 + 144 = x²
225 = x²
√225 = x

Answer:
cummutative
Step-by-step explanation:
Answer:
x=-12
Step-by-step explanation:
First subtract 2x on both sides. and you'll have x+5=-7.
Second subtract 5 on both sides, it will equal you x=-12
