Round to the nearest tenth :)

Good morning

Surface area (rounded to the nearest tenth) = 193.3 in²

Step-by-step explanation:

Surface area of this prism = 2×(base’s area) + lateral area

base’s area = (1.9 × 7)/2 = (1,9×7)÷2 = 6.65

lateral area = 12×(7+3+5) = 180

then

Surface area of this prism = 2×(base’s area) + lateral area

                                           = 2×(6.65)+180

                                           = 193.3

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.

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
