What is the perimeter of triangle DEF?
Answer choices:
90 cm
40 cm
45 cm
9 cm

Answer:

B

Step-by-step explanation:

First off, we see that x ≥ -2. That little horizontal line right under the > sign indicates that x is "greater than or equal to" -2. Because we want to include -2 in the solution set, the dot on the number line at -2 should be shaded in.

This already eliminates A and D.

Now, we're left to choose between B and C.

Well, we know that x is greater than or equal to -2, so possible values of x should be numbers that are more positive than -2, or that point in the positive direction. That's exactly what B illustrates, so that's our answer.

Answer:

6x^3+7x^2+2x

Step-by-step explanation:

Answer:

D) 6x³ + 7x² + 2x

Step-by-step explanation:

2x × 3x² = 6x³

2x × 2x = 4x²

1 × 3x² = 3x²

1 × 2x = 2x

Collect like terms to get

6x³ + 7x² + 2x

Answer:

Mr. Patio paid $312.00 for the three watches

Step-by-step explanation:

The price of one of the Casio G-Shock watches that  Mr. Patel bought his 3 friends for Christmas is $39.91.

For Mr. Patio to have bought this watch for each of his 3 friends, we have that the cost will be multiplied by three. He is spending three times the amount he would have spent if he is buying for only a single person.

Cost = 39.91 X 3 =$312.00

Mr. Patio paid $312.00 for the three watches

Answer:

Polynomials are classified according to their number of terms. 4x3 +3y + 3x2 has three terms, -12zy has 1 term, and 15 - x2 has two terms. As already mentioned, a polynomial with 1 term is a monomial. A polynomial with two terms is a binomial, and a polynomial with three terms is a trinomial.

Step-by-step explanation:

Examples to help:

2a + 4      (Unlike terms cannot be simplified)

4a + 3b    (Unlike terms cannot be simplified)

6a – 3a = 3a

8b – 8b = 0

5a – 3      (Unlike terms cannot be simplified)

Answer:

A senior citizen costs $8

Step-by-step explanation:

Represent senior citizens with S and children with C.

The first day is represented as:

[tex]3S + C = 38[/tex]

The second day is represented as:

[tex]3S + 2C = 52[/tex]

Required

Solve for C and S

Make C the subject in the first equation

[tex]C = 38 - 3S[/tex]

Substitute 38 - 3S for C in the second equation

[tex]3S + 2(38 - 3S) = 52[/tex]

[tex]3S + 76 - 6S = 52[/tex]

Collect Like Terms

[tex]3S - 6S = 52 - 76[/tex]

[tex]- 3S = -24[/tex]

Divide through by -3

[tex]S = 8[/tex]

Recall that: [tex]C = 38 - 3S[/tex]

[tex]C = 38 - 3 * 8[/tex]

[tex]C = 38 - 24[/tex]

[tex]C = 14[/tex]

Hence, a senior citizen costs $8

Answer:54

Step-by-step explanation:

Answer:  The choice will be any equation where the slope is the same and the y-intercept is different.

[tex]y=\frac{5}{6}x + b[/tex]

Step-by-step explanation:  Using slope-intercept form, y = mx + b,

m is the slope, b is the y-intercept.

Parallel lines will have the same slope.

So, you are looking for another equation that has 5/6 as the coefficient of x.

It could be an equation in the form 6y + 5x = _b_ where the constant, b, could be anything except -42, as that would be an identical line, not parallel.

Answer:

Well the original price would be $44

Step-by-step explanation:

So make an equation

Lets make X stand for the price before the deduction

so x-x(0.3)=30.80

Subtracting the X by x(0.3) would tell us the price, the 0.3 stands for 30 percent and we know its 30 percent of X so we subtract that since 0.3x would give the change

Now just solve the equation

You’ll get 44.

divide second equation by -3

3x+2y=1

other equatin is

3x+2y=1

since same equation, they are same line and lines are infinite so infinite solutions is answe

Answer:

No solution

Step-by-step explanation:

PEMDAS = distribute first.

9x+99=9x+3

Subtract 9x from both sides

99=3

Impossible so no solution.

Step-by-step explanation:

Answer:

The answer is D on edge.

Step-by-step explanation:

answer:

the answer is -3 and 8

Step-by-step explanation:

we will place -3 in the equation

(x+3)(x-x)=0

(-3+3)=0 (because -3+3 will cut down together)

we will place two 8(eights) in the equation

(8-8)=0

final answer is

(0)(0)=0

so -3 and 8 fits well in the equation

Answer:

70 ounces

Step-by-step explanation:

We can solve the weight of 35 candy bars by first finding the weight of one and multiplying by 35.

If 13 candy bars each weigh 26 ounces, one will weigh 2. We can write this out as shown:

13x = 26

x = 2

Now we simply multiply by 35 to get the total weight of 35 candy bars:

35x = 35(2) = 70

Answer:

7.4:1

Step-by-step explanation:

The rate of patrons to advertising dollar is7.4 patrons per dollar.

A rate is a comparison between two quantities that's calculated by dividing one quantum by the other. The quotient a/ b is appertained to as the rate between a and b if a and b are two values of the same kind and with the same units, similar that b isn't equal to 0. rates are represented by the colon symbol(). As a result, the rate a/ b has no units and is represented by the memorandum ab.

Given:

The colosseum has spent roughly $2.5 million on advertising over that period for 100 events.

So, the rate of patrons to advertising

= 18.5 million patrons to $2.5 million

= 18.5/2.5

= 7.4 patrons per dollar

Answer:

The correct answer is C, 68in².

Answer:

68

Step-by-step explanation:

The are of the  square is 3*3 = 9

Since we have two squares we need to mulitply by 2

9*2 = 18 is the total area of the squares

if you draw a line from the one square to the other you make a rectangle in the middle

the are of the rectangle is 10*3 which is 30

Two triangle has appared as we draw the line from one square to the other square.

The height of the traingle is (7 - 3)/2 which is 2

(2*10) / 2 =  which is 10

Since we have 2 triangle we get result as 2*10 = 20

20+30+18 = 68
