<em><u>Option A</u></em>
<em><u>The solution is:</u></em>
<em><u>Solution:</u></em>
We have to solve the equation f(x) = 0
Let f(x) = 0
Solve the above equation
Take square root on both sides
Thus the solution is found
Solution:
<u>Step-1: Find the GCF of both terms (Only for constants).</u>
- 60 = 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
- 40 = 1, 2, 4, 5, 8, 10, 20, 40
<u>We can see that 20 is the highest factor that is common in both numbers.</u>
<u>Using the GCF, factor the distributive property.</u>

Answer:
ft tall
Step-by-step explanation:
We must follow the indications:
Ryan is 4 1/2 ft. tall.
Ryan =
He is 3 in. taller than his sister Lizzie. to find how tall is Lizzie we need to substract 3 inches from the height of Ryan, but we can only substract the quantities if they are in the same units.
Thus we convert the 3 inches to feet, since we 1 feet = 12 inches:
so the height of lizzie:
we convert the first mixed number to fraction by multiplying 4 by 12 and adding the numerator 1:
the subtraction becomes:
Lizzie is 23/6 ft tall.
She is 3/4 of a foot taller than her sister Emma, thus we must substract 3/4 from the height of Lizzie to find the height of Emma:
Emma is ft tall.
The answer is 1/10 you move the decimal over 2 twice to the left
