-3(y + 5) + 3(2y + 6)
-3y - 15 + 6y + 18
3y + 3
Answer:
3y + 3
Hope this helps.
The 2 small black lines through the sides of the triangle indicate that the 2 sides are the same length.
Because the 2 sides are the same the 2 bottom angles are also the same.
This means that 9x +3 = 84
Now we can solve for x:
9x +3 = 84
Subtract 3 from each side:
9x = 91
Divide both sides by 9:
x = 81 / 9
x = 9
2m 10cm = 210cm
Perimeter = 2(length+width)
P = 2(210+45)
P = 2(255) cm
P=450 cm
Therefore, the rectangle's perimeter is 450 cm.
Answer:
Number 2
Step-by-step explanation:
The reason is because you are multiplying 10 by 5 and three this what it would look like
10(5+3)
10( Times) 5= 50
10(times) 3 = 30
50+30
This question is extremely hard for me to understand I don’t know why there are so many + and -. Have a good day.
