Answer:
A
Step-by-step explanation:
you do 3.6 times both the cm or number and you get 14.4 cm and 5.4 cm
First you would need to 8x5 witch is 40 so 40 would be you're answer to week 5.
Then do the same with week 6 so you'd do 8x6 witch is 48 so 48 would be you're answer to week 6.
Finally for week 7 you would do 8x7 witch is 56 so 56 would be you're answer to week 7 .

<u>Solution for question 1:</u>
Put it in this format:
Solving;
2(²-³) × 10^(15-9)
2^-1 × 10^6 = 1/2 × 10^6
That gives 5 × 10^5
<u>Solution to question 2:</u>
Solving;
2^(1 - 2) × 10^(-5 + 12)
= 1/2 × 10^7
That gives;
5 × 10^6
Answer:
Step-by-step explanation:
8x² + 2(x²-1) = 8x² + 2*x² - 2*1
= 8x² + 2x² -2
= 10x² -2
Like terms: 8x² , 2x²
