How high is a stack of library books if one book is 1 3/8 in. high, the second book is 1 5/6 in. high, and the third is 1 2/3 in. high? Explain how you solved this problem.

3 7/8 inches high

Step-by-step explanation:

You convert mixed numbers into improper fractions and use the LCM property in order to add all the numbers together

step-by-step explanation:

it's is b

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
