Step-by-step explanation:
The rule is to add 5 to each number to make next number
1 4 9 16 21 26 31 36 41
Answer:
(x - 3)(x - 7)
Step-by-step explanation:
Please use the symbol " ^ " for exponentiation: x^2 - 10x + 21.
Note that 3*7 = 21 and that 3+7 = 10. These are the clues we need to factor x^2 - 10x + 21. If we factor by grouping, we get:
x^2 - 10x + 21 = (x - 3)(x - 7). Note how -3x and -7x add up to -10 x (as they should), and that -3 times -7 is +21 (as required).
Combine like terms: (14-134)y+112+2-2=-120y+112
So the simplified form of the expression is -120y+112

Answer:
7x=42°
8x=48°
Step-by-step explanation:
Sum of all interior angles in a triangle=180°
90+8x+7x=180
90+15x=180
15x=180-90
15x=90
x=90/15
x=6
