1.) There are 17 pencils in every pencil holder. How many pencils are there in 3 pencil holder?

Using unitary method :

then,

17 × 3 = 51 pencils

Step-by-step explanation:

hope it helps u..

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
