Find the area of the triangle 5.7 m
4 m
5 m
4 m
3 m

a) 12m2
b) 15m2
c) 14m2
d) 13m2

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo

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

hint: which coefficient is a multiple of 360°?
