At her school’s spring carnival, Leslie is in charge of the balloon-launcher contest. In this contest, each team builds a catapult to launch water balloons at a target. Leslie gives a bucket of 12 water balloons to each team in the contest. In all, she gives out a total of 48 water balloons. Which equation can model this situation for n, the number of teams in the contest? a 48 = 12 + n b 48 = 12n c 48 = 12 - n d 48 = 12/n

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
