Answer:
The answer is y.
Step-by-step explanation:
Since carter multiplies by 10 and then by 2 and adds the two, here we have been given 16 * 12
Step 1: Carter would first multiply the number by 10. This would be = 16*10
Step 2: Carter would multiply the number by 2. This would be = 16*2
Step 3: He would add the two. This would be = (16*10) + (16*2)
Carter's solution would be:
=16*12
=(16*10) + (16*2)
= 160 + 32
= 192
(x³ - 2)(3x² - 1) + r = 3x⁵ + 3x³ + 2x² + x + 2
x³(3x² - 1) - 2(3x² - 1) + r = 3x⁵ + 3x³ + 2x² + x + 2
x³(3x²) - x³(1) - 2(3x²) + 2(1) + r = 3x⁵ + 3x³ + 2x² + x + 2
3x⁵ - x³ - 6x² + 2 + r = 3x⁵ + 3x³ + 2x² + x + 2
-x³ - 6x² + 2 + r = 3x³ + 2x² + x + 2
-6x² + 2 + r = 4x³ + 2x² + x + 2
2 + r = 4x³ + 8x² + x + 2
r = 4x³ + 8x² + x
Answer:
the answer is 123 degrees
Step-by-step explanation:
All of the angles added together should equal 360 degrees, so you just have to subtract all of the angles from 360. 360 - 114 - 80 - 43 = 123.
1.) -15.9, -15.2, -3.6, 3.6
2.) second one is already correct
3.)-2.3, -2.03, 2.03, 3.0
