Answer:
x = ±6i sqrt(2)
Step-by-step explanation:
6x^2 + 432 = 0
Subtract 432 from each side
6x^2 =- 432
Divide by 6
6x^2 /6 =- 432/6
x^2 =-72
Take the square root of each side
sqrt(x^2) = ±sqrt( -72)
x = ±sqrt(-1) sqrt(2*36)
We know the square root of -1 = i
x = ±i sqrt(2*36)
x = ±i sqrt(36) sqrt(2)
x = ±6i sqrt(2)
Answer:
18
Step-by-step explanation:
3 multiplied by 6 = 18
Answer:
8
Step-by-step explanation:
AB is 3 cm and AC is 2 cm, and since triangle ABC is an isosceles triangle, BC can either be 3 cm or 2 cm. We want the longest perimeter possible, so make BC 3 cm, and add the side lengths to find the perimeter.
P = 3 + 3 + 2 = 8.
6(x + 2) = 3(2x + 4)
STEP ONE:
Multiply both sides
6x + 12 = 6x + 12
STEP TWO:
You can see both sides are identical, therefore you can conclude there are infinite solutions
