addition to their standard fireworks, the organizers are including special fireworks that will go off at
specific times, as shown in the table:
exas
firework
timing
white chrysanthemum
every 2 minutes
blue bloom
every 3 minutes
red explosion
every 5 minutes
if the organizers want to start and end the fireworks show with all three of these special fireworks
going off together, how long could the fireworks show be? explain your reasoning.

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*

step-by-step explanation:

hey pal. the answer is b plz mark as brainliest

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81
