Answer:
47.66666667
Step-by-step explanation:
58- 10 1/3= 47.66666667
Answer:
A. (-5, 0) and (-2, 0)
Step-by-step explanation:
Assuming you mean x^2 + 7x + 10. Simply graph using Desmos and locate where the graph crosses the x-axis! :)
Step 1: Group this into two groups:

When you do that, be sure to group the "–" into the group with the 9 and make sure there's "+" between the groups.
Step 2: Factor out the GCF from both individual groups:

Step 3: Notice both groups have that (h+2)? That's a new GCF between the two groups, so factor that out:

Step 4: That
piece can be factored further, since it's a difference of squares:

Now it's factored.
Answer:
2√3
Step-by-step explanation:
5y2+20=80
Step 1: Subtract 20 from both sides.
5y^2+20−20=80−20
5y^2=60
Step 2: Divide both sides by 5.
5y^2
/5 =
60/5
y2=12
Step 3: Take square root.
y=√12
y=2√3
