Choose a number between 55 and 101 that’s is a multiple of 3, 5, and 9

90.

Step-by-step explanation:

Factors 3, 5 and 9.

The number must end in 0 or 5 ( because 5 is a factor).

Try 90:-

90 = 2 * 3 * 3 * 5  so it is divisible by 3, 5 and 9.

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
