She grocery shops 4 times a month. wat inequality can help to find the possible values of x the amount she can spend at the grocery store during each shopping trip. #2. if x =5 what inequality is true ( A. -2x>12 B. x - 2 < 7 C. 2x > 12 D. x - 7 > 2). #3. what is the value of x in this equation -4x = 42? hope anyone can help thx.

step-by-step explanation:

a and d

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
