I don’t really know what the answer is but I’ll try so - 6/7 = 6/7 3 15/44 = - 3 15/44 -2 5/22
Yes they are the same value because the 4 is in the tenths place in bother decimals. 0.4 is just a shortened way of writing 0.40.
Answer:
A=2a2+4ah=2·92+4·9·10=522
Problem 13
If we want to multiply (x^3-3x^2+2x) with (x^3-2x^2+x), then we can set up a diagram shown below. The terms are along the outside. The stuff inside is the result of multiplying each pair of outer terms.
- Example: x^3 times x^3 = x^6 in the top left corner
- Another example: 2x times x = 2x^2 in the bottom right corner.
This is known as the box method to keep track of all the terms multiplied.
Once the table is filled out, we add up each term inside the boxes. Combine like terms if possible. Notice that I color-coded the like terms (eg: the x^3 terms are in green boxes).
The final answer is x^6 - 5x^5 + 9x^4 - 7x^3 + 2x^2
