Answer:

the triangle

Step-by-step explanation:

The perimeter is the sum of the all sides of the shape.

Triangle:

3√147+2√108+2√48+3√75+ 6√12

147=49•3, 108=36•3, 48=16•3, 75=25•3, 12=4•3 that means

√147=7√3, √108=6√3, √48=4√3, √75=5√3, √12=2√3

perimeter=3•7√3+2•6√3+2•4 √3+3•5√3+6•2√3=68√3

Square:

4•1/3•√63=4/3•√9•√7=4√7

Rectangle:

2•1/4√100+2(2√48+4√75)=

5+2(8√3+20√3)=5+56√3

Now, if you use a calculator, you will find that the greatest perimeter is for the triangle shape.

What is the product of (-a+3)(a+4)?<br><br> a^2-a+12<br> a^2-a-12<br> -a^2-a-12<br> -a^2-a+12
Damm [24]

Answer:

-a^2 + -a + 12

Step-by-step explanation:

Expand the following:

(3 - a) (a + 4)

(3 - a) (a + 4) = (3) (a) + (3) (4) + (-a) (a) + (-a) (4):

-a a + 3 a - 4 a + 3 4

3×4 = 12:

-a a + 3 a - 4 a + 12

-a a = -a^2:

-a^2 + 3 a - 4 a + 12

Grouping like terms, -a^2 + 3 a + 4 (-1) a + 12 = -a^2 + (3 a - 4 a) + 12:

-a^2 + (3 a - 4 a) + 12

3 a - 4 a = -a:

Answer: -a^2 + -a + 12
