Answer:
a. 32 ft²
Step-by-step explanation:
Given:
L = 3 ft
W = 2 ft
H = 2 ft
Required:
Surface Area of the box
SOLUTION:
Surface area = 2LW + 2LH + 2HW
Plug in the values
Surface area = 2(3*2) + 2(3*2) + 2(2*2)
SA = 12 + 12 + 8
SA = 32 ft²
Answer:
p=13, k = 3.25
Step-by-step explanation:
First, determine p:
Use this value in the second equation
and write the condition for that equation having equal roots, i.e., its determinant must equal 0:
Add 12 to both sides
6x^2 = -1 + 12
Simplify -1 + 12 to 11
6x^2 = 11
Divide both sides by 6
x^2 = 11/6
Take the square root of both sides
x = ±√11/6
Simplify √11/6 to √11/√6
<em>x = ±11/√6</em>
<u>Answer: B) x = ±11/√6</u>
The answer is y=3 I believe
