1. Flicks for Four Families
Four families go to the cinema. The Reid family
take 2 adults and 2 children for £18; the McGhee
family take 1 senior, 2 adults and 1 child for
£18.50; and the Griffiths family take 1 senior and
3 adults for £19.50. How much will it cost for the
Linton family to take 1 senior, 2 adults and 3
children?

the correct is answer is a 9-sided polygon!

part d

step-by-step explanation:

theresa talked her parents into getting sd cards for her phone and her brother’s phone. inserting an sd card into a phone gives it more storage. they both get 8-gigabyte sd cards. how many bits of storage come with each sd card? type your answer in both scientific and standard notation.

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

answer is (b.
