Answer:
52
Step-by-step explanation:
1) Simplify the inner most parentheses:
35 + [16 - 7 + 8}
2) Perform the operations inside the brackets:
35 + [17]
3) Add
52
4.5 x 10^6 = 4,500,000
2.1 x 10^8 = 210,000,000
Therefore, 4.5 x 10^6 < 2.1 x 10^8
Answer:
-20x+8
Step-by-step explanation:
Step 1: rearrange the equation
16x^2 - 3x^2 - 7x - 13x +8
Step 2: solve the equation
16x^2 - 3x^2 = 13x^2
-7x - 13x = -20x
(the +8 will stay the same)
so when we put it all together it gives us
13x^2 - 20x + 8
