<span> a⁴(3a² - 2a + 1)
We just have to multiply each term inside the parentheses by a⁴ .
a⁴</span><span>(3a² ) = 3a⁶
a⁴</span><span>( - 2a ) = -2a⁵
a⁴</span><span>( 1) = a⁴
Now, just addum up : 3a⁶ - 2a⁵ + a⁴</span>
Again, decimals and fractions represent all the values in between integers. Decimals are simply one step more of simplification from fractions.
now, let's notice the minor arc of 26x°, let's recall that a circle has a total of 360°, thus if the minor arc is 26x°, then the major arc has to be the difference of 360 and that much, namely 360 - 26x.
Check the picture below.
Answer:
x=15
Step-by-step explanation:
2x+150=180
2x=39
x=15
