Answer:
Were you given a graph or do you have one you can use?
- If you do, all the need to do is plot the points that are shown in the question. -Secondly, You need to join the lines together.
-After that, you need to find the 'middle point' of each line. Eg. If I had a line with 4 spaces in-between it, I would put a point or cross after the 2nd space.
Hope that helped? Sorry if it's too confusing and was useless.
<u><em>In the image the blue shape is the rectangle and the red shape is the rhombus/tilted square.</em></u> (MY DRAWING IS BAD I KNOW DON'T SAY ANYTHING ABOUT IT) Anyways. I still feel like you need to do it yourself as this was assigned to you so get some paper and draw this graph out. Let me know if you need more help!
Ok so 4892=83(52)+64x
4892=4316+64x
576=64x
9=x
So he should 9 snowboards.
Step-by-step explanation:
120/20=6g
50/20=2.5g
170/20=8.5g
for one shortbread ^^
6*50=300g
2.5*50=125g
8.5*50=425g
for 50 shortbread ^^
Answer:
3(a - b)(a + b)
Step-by-step explanation:
Factorize: (2a - b)² - (a - 2b)²
- Different of Perfect a Square rule: a² - b² = (a + b)(a - b)
(2a - b)² - (a - 2b)² = [(2a - b) + (a - 2b)] × [(2a - b) - (a - 2b)]
1. Distribute and Simplify:
Distribute the (+) sign on the first bracket and simplify: [(2a - b) + (a - 2b)] → 2a - b + a - 2b → (3a - 3b)
Distribute the (-) sign on the first bracket and simplify: [(2a - b) - (a - 2b)] → 2a - b – a + 2b → (a + b)
We now have:
(3a - 3b)(a + b)
2. Factor out the Greatest Common Factor (3) from 3a - 3b:
(3a - 3b) → 3(a - b)
3. Add "(a + b)" back into your factored expression:
3(a - b)(a + b)
Hope this helps!
Each person will get 6/8. Hope this helped.
