Answer: -135
Explanation:
1) I will use synthetis division
2) Write the coefficients of the divisor in order
1 -3 7 5
3) Dividing by x + 4 => use x = - 4
4) Division:
| 1 -3 7 5
|
- 4 | -4 +28 - 140
-------------------------------
1 -7 35 - 135
5) The last number is the remainder: - 135
THE ANSWER TO X IS 14
1-3x+15
-3x=12/3=4
2-5x-45
+5=50/5=10
3-4+10=14
Answer:
3² or 9
Step-by-step explanation:
Step 1: Add exponents
![\frac{3^{12}}{3^{10}}](https://tex.z-dn.net/?f=%5Cfrac%7B3%5E%7B12%7D%7D%7B3%5E%7B10%7D%7D)
Step 2: Subtract exponents
You should get 3² because of exponent rules. Remember when you multiply exponents you add the powers and when you divide exponents you subtract the powers.
I think it's a rectangle block because the surface is flat on all the sides.
