Which number sentences show how to solve the problem?
the garden club wants to buy 48 rose bushes for 4 city parks. each rose bush costs $12. each park gets the same number of rose bushes. how much will the rose bushes for each park cost?
choose all answers that are correct.
a.
12 ÷ 3 = 4 and 48 × 4 = 192
b.
12 × 48 = 576 and 576 ÷ 4 = 144
c.
48 ÷ 12 = 4 and 48 × 4 = 192
d.
48 ÷ 4 = 12 and 12 × 12 = 144

answer

you start with $5 and save $10 a week until you have at least $45wer

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
