Ijust learned about like terms today. 30 points if you me do

this is an example from the website below

Step 2: Combine the coefficients.

5h + 11g + 1h - 8g.

(5 + 1)h + (11 - 8)g.

6h + 3g.

Step 1: Organize your like terms.

5x + 8x + 10x2 - 7x2 - 4x.

Step 2: Combine the coefficients. (5 + 8 - 4)x + (10 - 7)x2 9x + 3x2 Related Links: Combining Like Terms Worksheets. Combining Like Terms Quiz. Algebraic Expressions.

I would do it for you but I believe you can do it on your own with these instructions

1: 5n, 2n and n are like terms, 6m and 2m are like terms and 4n (to the power of 3 has no like term)

2: 2g, 3g and g are like terms, nothing else is like terms

3: 7x (to the power of 2) and 3x(to the power of 2) are like terms, and 2 and 3 are like terms, also 3x and x are like terms.

Now Combining

1: 3v and 2v can be combined to make 5v + w = 6v + 8 = 14v - 2 = 12v

2: 8c(to the power of 2) + 2c(to the power of 2) = 10c(squared) You can also combine 6c and 5c = 11c, so 11c + 10c(squared) and 10c(squared) is equal to 10c + 2 so 12c + 11c = 23c

3: so 5e and 2e can be combined to make 7e and 8 and 2 and 13 can be combined to make 23, and the rest cannot be combined, so it is 23 + 7e + 3z = 30e

Hope this helps! :D

Step-by-step explanation:

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).

is there any photos or whatever?
