Answer:  B

Step-by-step explanation:

The given expression is the square of a binomial, such that:

(2x + 1)^2 = 4x^2 + 4x + 1

Then the correct option is C.

We want to see if:

(2x + 1)^2

Is equivalent to (4x^2 + 1).

First, this is false, let's prove that.

We have the square of a binomial (2x + 1)^2. Remember the general formula:

(a + b)^2 = a^2 + 2ab + b^2

So if we apply this to our expression we get:

(2x + 1)^2 = (2x)^2 + 2*2x*1 + 1^2 = 4x^2 + 4x + 1

Then, the correct option is C.

Greetings Mrs.(name here)!

I got my recent test back and I was wondering why this question was incorrect.

For #4, I was sure that you had to find the square root and then multiply by pi, but apparently that's not what some people did and they got it correct.

How do I properly do this question?

6/10 or 0.6 or 60% Hopefully this helps

Answer:

The fractions equivalent to 3/5 are 6/10, 9/15, 12/20, etc. Equivalent fractions have the same value in the reduced form. Explanation: Equivalent fractions can be written by multiplying or dividing both the numerator and the denominator by the same number.

Step-by-step explanation:

Answer:

(0,-4), (2,6), and (4, 16) are solutions to this equation.

Yes the point (-5,-29) is a solutions

Step-by-step explanation:

(-5,-29) is a solution because if you plug in -5 for x, y will equal to the y in the ordered pair.

a) Three ordered pairs (0, -4), (2, 6), and (-3, -19) that are solutions to the linear equation y = 5x - 4.

b) We verified that the point (-5, -29) is a solution to the equation by substituting its x and y values and getting a true statement.

a. To find ordered pairs that are solutions to the linear equation y = 5x - 4, we can simply substitute different values of x into the equation and calculate the corresponding y-values.

Let's choose three different values for x and calculate the corresponding y-values:

When x = 0: y = 5(0) - 4 = -4

So, the ordered pair is (0, -4).

When x = 2: y = 5(2) - 4 = 6

So, the ordered pair is (2, 6).

When x = -3: y = 5(-3) - 4 = -19

So, the ordered pair is (-3, -19).

b. To test whether the point (-5, -29) is a solution to the linear equation y = 5x - 4, we need to check if substituting x = -5 into the equation gives us y = -29.

Let's do the calculation:

y = 5(-5) - 4

y = -25 - 4

y = -29

Since y = -29 when x = -5, the point (-5, -29) is indeed a solution to the linear equation.

Answer:

y⁶ (I think you enter just 6 in your problem)

64x¹⁸y⁶ (Simplified)

In the Simplified problem above y has an exponent of 6.

(I named the empty line y)

y²= 9²+5²

= 81+25

=106

y= V106

y≈10.30

x²= 4²+y²

= 4²+ (V106)²

= 16+106

x≈11.05

Using proportions, it is found that the correct option regarding how much faster she is in the first 5 minutes compared to the last 5 is given by:

B. 0.3 mile/minute faster

A proportion is a fraction of a total amount

Researching the problem on the internet, it is found that on the first 5 minutes, she bikes 2 miles, hence the ratio is:

r1 = 2/5 = 0.4 miles/minute.

On the last 5 minutes, she bikes 0.5 miles, hence:

r2 = 0.5/5 = 0.1 miles/minute.

The difference is given by:

D = 0.4 - 0.1 = 0.3 miles/minute.

Which means that option B is correct.

Answer:

2/81

Step-by-step explanation:

Firstly find out the common ratio.

And then the general term.

And at last you can find any term(7th term in this case).

The 7th term of the sequence will be 13122.

We have the following sequence -

18, 6, 2 ...

The nth term of the geometric sequence will be a[n] = arⁿ ⁻ ¹.

a[7] = 18 x 3⁶

a[7] = 18 x 9 x 9 x 9

a[7] = 13122

Therefore, the 7th term of the sequence will be 13122.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Area of figure I = length *width

                          = 4 * 5

                          = 20 m²

Figure II is a trapzium.

a and b  are the parallel sides. a = 21 m

b = 20 - 5 = 15 m

h =  3 + 4 = 7 m

[tex]\text{area of figure 2 = $\dfrac{(a + b)*h}{2}$}[/tex]

                       [tex]=\dfrac{(21+15)*7}{2}\\\\\\=\dfrac{36*7}{2}\\\\\\= 18*7\\\\= 126 \ m^{2}[/tex]

Area of the figure = 20 + 126

                               = 146 m²

Answer:

146 m²

Step-by-step explanation:

Formulae

Area of a rectangle = width x length

Area of a triangle = 1/2 x base x height

Divide the figure into 2 rectangles and a triangle (see attachment).

Area of Rectangle 1 = 4 x 5 = 20 m²

Area of Rectangle 2 = (3 + 4) x (20 - 5) = 105 m²

Area of triangle 3 = 1/2 x (21 + 5 - 20) x (3 + 4) = 21 m²

Total area = 20 + 105 + 21 = 146 m²

to find the reciprocal just switch the numerator and the denominator.

Answer:

1 and 6

5 and 7

Step-by-step explanation:

Supplementary angles are 180 degrees and so is a linear pair

1 and 6 add up to 180 degrees meaning they are supplementary. Angle 1 and angle 2 are a linear pair so 180-120=60 which is the degree of angle 1, angle 2 corresponds to angle 6, so angle 1 + angle 6 would equal 180 degrees. (120+60)

5 and 7 are a linear pair which automatically makes them supplementary

The others are vertical angles which don't add up to 180. (120+120=240)(60+60=120)
