Construct a triangle with side lengths of 4 inches and 3 inches and an angle of 90° what is the length of the third side of the triangle

5

Step-by-step explanation:

Im assuming they want the hypotenuse of the triangle so use Pythagorean theorem.

4^2+3^2= c^2

16+9=c^2

25=

√25= √c^2(

5=c

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

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
