Step-by-step explanation:
hope this helps!!
3u+ 9 is the right answer, since thier not like terms you can’t add them
The answer is isosceles triangle
Here, You need to substitute the value of x, and y, in the equation then check if L.H.S is equal to R.H.S or not. If they are equal then, ordered pair was correct, otherwise they are not applicable.
75) Here, oly option D can fit i the equation, we can check:
3(-5) -2(-1) = -15+2 = -13 = R.H.S
So, the pairs are valid.
76) Here, only option D is your answer,
4(2) - 4 = 8 - 4 = R.H.S
Do the same thing in every equation!
Hope this helps!
Simplify and add everything.
You will get 1089822 as the final answer.
