If denomenators are same, we can add
remember
(a/b)+(c/b)=(a+c)/b
so
(3y/2)+(9/2)=(3y+9)/2
Answer:
so, the width of the poster is 8.185 inches [rounded] / √67 inches
and the length of the poster is 13.185 inches [rounded] / √67 + 5 inches
Step-by-step explanation:
( area can be found with the formula l × w [length × width] )
I will call the width "x"
w · l = 72
x · x + 5 = 72
- 5 - 5
x · x = 67
x² = 67
√x² = √67
x ≈ 8.185
(x = √67)
so, by adding 5 inches, we get that
x + 5
8.185 + 5 [√67 + 5]
length = 13.185
so, the width of the poster is 8.185 inches [rounded] / √67 inches
and the length of the poster is 13.185 inches [rounded] / √67 + 5 inches
Answer:
I think it's 7+(-2). Or else it could be 7-(-2) because one of the arrow is going up 7 and one of arrow is going down -2, and as they said add or subtract that's why I provide both options.
