<h3>(2-1) + 3² ÷ 3.</h3>
<em>To divide powers with the same base, subtract the exponent in the denominator from the exponent in the numerator. Subtract 1 from 2 to get 1.</em>
<h3>2 − 1 + 3¹</h3>
<em>Subtract 1 from 2 to get 1.</em>
<h3>1 + 3¹</h3>
<em>Calculates 3 to the power of 1 and gets 3.</em>
<h3>1 + 3</h3>
<em>Add 1 and 3 to get 4.</em>
<h3>4</h3>
The correct option is Alternative "C".
Answer:
k = 11/3
Step-by-step explanation:
If the line is tangent to the curve, then Δ = 0.
______________
Remembering:
Δ>0 two different points of intersection x' x''
Δ=0 one point of intersection x' = x''
Δ<0 two different points of intersection in the complex plan x' and -x'
______________
As the line and the curve have one point of intersection, which is (x, y), we can make a equality between them:
2x + k = 3x² + 4
0 = 3x² - 2x + (4 - k)
Now we can use the Δ=0 (Δ= b² - 4ac)
Δ = 0 = (-2)² - 4.3.(4-k)
0 = 4 - 48 + 12k
12k = 44
k = 44/12 = 2 . 22 /3. 2.2 = 22/3.2 = 11/3
k = 11/3
You know the number has to be divisible by 11. You also know the number is between 100 and 200.
You can list the multiples of 11 in this interval.
110, 121, 132...
You have your answer. The total price is 132 dollars, and the missing digit is 3.
£1.56 because 20 % of £1.30 = 26 p so 26 + 130 = £1.56
Greetings!
Let l represent the
length of the rectangle.
Let w represent the
width of the rectangle.
Isolate for the l in Equation #2.
Substitute
Equation #2 into Equation #1.

Add 2 to both sides.
Divide both sides by
8.
The Answer Is:
The Width is
6 units and the Length is
17 units.
Hope this helps.
