Answer:
measure angle D = 62
Step-by-step explanation:
as the sum of measures of triangle =180
then (8x-40)+(4x-10)+(3x+20)=180
15x-30=180
x=(180+30)/15=14

Y=D=3*14+20=62
So for this, you will be dividing 9.3/3.1 and 10^34/10^17 separately.
Starting with 9.3/3.1, that equals 3
Now with 10^34/10^17, remember that the rule with dividing exponents with the same base is that you are just subtracting the exponents. In this case: 10^(34 - 17) = 10^17
Now we put the two quantities together, and your answer will be 3 x 10^17, or the second option.
Answer:
f(x) = (x+6)² - 10
Step-by-step explanation:
To write the equation in vertex form we, we need to use completing square method.
f(x) = x²+ 12x + 26 = (x² + 2*x*6 + 6²) - 6² + 26 = (x+6)² -36 + 26 =
= (x+6)² - 10
f(x) = (x+6)² - 10
