Answer:
12 inches of red ribbon + 7 inches
therefore the length of a blue ribbon is = 19 inches
You first substract 18 from both sides so you get
10x<-20 you then divide by 10 so the answer is
x<-2
Answer:
The answer would be A
Step-by-step explanation:
1^2=1×1= 1
2^2 =2×2=4
3^2=3×3=9
4^2=4×4=16
Therefore,
√11 lies between 3 and 4
We have the following expression:
S = 6x ^ 2
We must clear x from the equation.
For this, we follow the following steps:
Step 1)
Pass 6 to divide:
S / 6 = x ^ 2
Step 2)
Square root on both sides:
+/- root (S / 6) = x
Step 3)
Multiply numerator and denominator by 6:
x = + / - root (6S / 6 * 6)
Step 4)
Rewrite expression:
x = + / - root (6S / 36)
Step 5)
Take root to denominator:
x = + / - (root (6S)) / 6
Answer:
x = + / - (root (6S)) / 6
