a, c and e are equivalent.

Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

Given

a.  (3.4a – 1.7b) + (2.5a – 3.9b)

b.  (2.5a + 1.6b) + (3.4a + 4b)

c.  (–3.9b + a) + (–1.7b + 4.9a)

d.  (–0.4b) + (6b – 5.9a)

e.  (5.9a – 5.6b)

The addition of the given polynomial.

Add a term with a and b term with b.

a.  (3.4a – 1.7b) + (2.5a – 3.9b)

3.4a - 1.7b + 2.5a -3.9b

5.9a - 5.6b

b.  (2.5a + 1.6b) + (3.4a + 4b)

2.5a + 1.6b + 3.4a + 4b

5.9a + 4.6b

c.  (–3.9b + a) + (–1.7b + 4.9a)

-3.9b + a - 1.7b + 4.9a

5.9a - 5.6b

d.  (–0.4b) + (6b – 5.9a)

-0.4b + 6b - 5.9a

-5.9a + 5.6b

e.  (5.9a – 5.6b)

5.9a - 5.6b

Thus, a, c, and e are equivalent.

Answer:

how do you solve it the problem

Explanation/Answer:

To convert, we need a common denominator.

So if, say, we multiply the denominator by 2, we must multiply the numerator by 2 as well.

1) 4/5+4/7

4x7/5x7 + 4x5/7x5

28/35+20/35

(Both have common denominators so we can add them)

28 +20/35= 48/35=1 13/35

2) 1/2+11/8

(We already have common denominator in one of the numbers so we only have to convert ONE of the fractions)

1x4/2x4+11/8

4/8+11/8=15/8= 1 7/8

3) 1/5+1/3

1x3/5x3+1x5/3x5

3/15+5/15=8/15

Hope this helped :D

Answer:
1. 48/35

2. 15/8

3. 8/15

Step-by-step explanation:

You have to make sure the denominator is the same before combining both fractions. Whatever you multiply by the denominator, you need to do to the numerator.

Substituting all the given values in the formula to find the third side of triangle :

Step-by-step explanation:

6 pages in 3 hours : ratio 6/3 = 2

8 pages in 4 hours : ratio 8/4 = 2

yes, the rates are proportional, as they represent simplified the same ratio.

Answer:

Yes, they are proportional

Step-by-step explanation:

Catalina:

Pages : Hours = 6 : 3 = 2 : 1

In 1 hour Catalina reads 2 pages

Joshua:

Pages: Hours = 8 : 4 = 2 : 1

In  1 hour, Joshua reads 2 pages.

So, they are in proportional.

Answer:

Reduce each side by 1/3, 9m would be 3m, 12m would be 4m, 15m would be 5m.

Step-by-step explanation:

To make a triangle a fraction smaller (such as 1/3, 1/4, or 1/6) just multiply the sides by the fraction. To make a triangle a fraction bigger, multiply it by the sides but then add the solution to the original triangle to get a triangle a fraction bigger.

Answer: Your new triangle would have the side lengths 3 m, 4 m, and 5 m.

Step-by-step explanation:

To make a triangle 1/3 as long as the original, you can multiply each side length by 1/3 (or simply divide each side by 3) to get the new side lengths.

9 ÷ 3 = 3

12 ÷ 3 = 4

15 ÷ 3 = 5

Therefore, the new triangle would have side lengths of 3 m, 4 m, and 5 m.

Answer:

Square side=40ft

Semi-circle diameter=39.98ft

Area of court=2276.69 ft^2

Step-by-step explanation:

The square section has a semicircle joined to it and the combined perimeter is 182.8 ft.

-Area of the square section is obtained by subtracting that of the semicircle from the total(only 3 sides of the square is used since one side is attached to the semi-circle)

Hence, the square's sides  has the dimension of 40 ft.

The semi-circle's diameter is calculated as:

Hence, the semi-circle's diameter is 39.98 ft

The area of the court is calculated as:

The court's area is 2,227.69 ft^2

Using exponential function concepts, it is found that the constant 1.0015 reveals that the quantity increases by 0.15% each decade.

An increasing exponential function is modeled by:

[tex]A(t) = A(0)(1 - r)^t[/tex]

In which:

In this problem, the function is:

[tex]f(t) = 9900(1.0015)^{10t}[/tex]

In which t is the time in decades.

The growth rate is r = 0.0015, as [tex]1 + r = 1.0015 \rightarrow r = 0.0015[/tex], hence the constant 1.0015 reveals that the quantity increases by 0.15% each decade.
