Answer:
Step-by-step explanation:
When you have four terms and 3rd degree equation (the highest power is 3) you will want to try to "factor by grouping"
Group together two terms, watch out for the negative signs!
x^3 + 2x^2-5x-10=0
(x^3 + 2x^2) - (5x+10)=0
Find a common factor in each group and factor it out. You're hoping that what is left in the parenthesis is the same in both cases.
x^2(x+2)-5(x+2)=0
Now you can factor out that (x+2) because it is both terms.
x^2(x + 2) - 5(x + 2)=0
~~~~ ~~~~
Pull these out.
What will be left is the x^2 and the - 5 (dont lose that - in front of the 5)
(x + 2)(x^2 - 5) = 0
If all you have to do is factor, then you're done. It is factored. But if you have to "solve" also, then put x+2=0 and x^2-5=0 and solve.
x = -2 and x = +- sqrt5
Answer:
Pic attached.
Step-by-step explanation:
Your slope is 
and your y-intercept is -3. Plot your y-intercept on the y axis at -3 and then go up 3 and over 2, plot another point.
Hope this helps! :)
<span> Measure the radius </span>Calculate the diameter Measure the distance from the center of the circle to the circumference. This is the radius of the circle. <span> Calculate the circumference</span> Multiply the radius of the circle in question by two to get the diameter. Multiply
pi by the diameter to get the circumference of the circle. For
instance, if the diameter of the circle is 20 centimeters, the
circumference of the same circle is the product of 20 centimeters and
3.14, which is 62.8 centimeters.

Answer:
<u>Δ MNO ≅ Δ PQR by ASA postulate</u>
Step-by-step explanation:
Δ MNO and Δ PQR are congruents because:
1. Their included sides MN and PR are equal (22 units = 22 units)
2. Their angles ∠M and ∠P are equal (100° = 100°)
3. Their angles ∠N and ∠Q are equal (35° = 35°)
<u>Now, we can conclude that Δ MNO ≅ Δ PQR by ASA postulate.</u>
