Answer:
Answer is x=3+0.05/5
Step-by-step explanation:
5x+19.95=35
We move all terms to the left:
5x+19.95-(35)=0
We add all the numbers together, and all the variables
5x-15.05=0
We move all terms containing x to the left, all other terms to the right
5x=15.05
x=15.05/5
x=3+0.05/5

Answer:
<em>a = 1 ; b = - 8 </em>
Step-by-step explanation:
x² + 2x - 7 = (x² + 2x + 1) - 1 - 7 =<u><em> (x + 1)² - 8 </em></u>
<em>a = 1 </em>
<em>b = - 8</em>
Step-by-step explanation:
16⁴ - 2¹³ - 4⁵
= 2¹⁶ - 2¹³ - 2¹⁰
= 2¹⁰(2⁶ - 2³ - 1)
= 2¹⁰(64 - 8 - 1)
= 2¹⁰ * 55
= 2¹⁰ * 5 * 11.
Since it contains 11 in its prime factorization, it is divisible by 11. (Proven)
