If f(x) = 3(x+ 5) +4/x, what is f(a+2)?

A. 3(f (a) + 5) +4/f(a)+2

B. 3(a + 7) + 4/a+2

C. 3(a + 2) + 4/a + 2

Answers

Answer 1

Answer:

B. 3(a + 7) + 3/(a + 2)

Step-by-step explanation:

Just substitute (a+2) in for every (x) in the equation:

f(a + 2) = 3 ((a + 2) + 5) + 4/(a+2)

           = 3 (a + 7) + 4/(a+2)

What is the area of this figura?​

Answers

Answer:

total area of the figure is: 1568 yd^2

Step-by-step explanation:

The area of the figure is the addition of the areas of a square and a rectangle:

The square on top that measures  28 yd times 28 yd, therefore its area is:

28^2 yd^2 = 784 yd^2

The rectangle at the bottom measures: 56 yd times 14 yd, therefore its area is:

Area rectangle = base x height = 56 yd x 14 yd = 784  yd^2

Then, the total area is the addition of these two:

Area of square + area of rectangle = 784 yd^2 + 784 yd^2 = 1568 yd^2

Answer:

C

Step-by-step explanation:

I think it would be easiest to see these numbers in decimal form to determine which number is the greatest and which is the smallest.

2 as a decimal=2.0

Square root of 7 as a decimal= 2.64575131106

1/3 as a decimal= 0.3333333333333333333333333333333333333333333...

So, 0.3333333...<2.0<2.64575131106

The length of a cuboid is one more than its breadth and the perimeter of its base is 18 cm. If its
lateral surface area is 54 sq. cm, find the volume of the cuboid.

Answers

Answer:

60 cm^3

Step-by-step explanation:

The computation of the volume of the cuboid is given below:

let us assume the length be l

and b the breadth

So

l = b + 1

And, the perimeter is

2(l + b) = 18

2l + 2b = 18

2b + 2 + 2b = 18

b = 4

And l = 5

Now

2(l + b) × h = 54

2(5 + 4 ) × h = 54

h = 3

Now the volume of the cuboid is

= l × b × h

= 5 × 4 × 3

= 60 cm^3
