Answer:

(12x+4)² and p²−6p+9

Step-by-step explanation:

From the given choices, we areto select the one that are squares of linear expressions

1) For the expression (12x+4)²

This is regarded as the square of 12x+4 since the expression 12x4 is enclosed in parenthesis

2) For the expression p^2−6p+9

Factorize;

p^2−6p+9

p^2−3p-3p+9

p(p-3)-3(p-3)

(p-3)(p-3)

(p-3)²

Hence p^2−6p+9 is a square of the expression p-3

This are the only two required expressions (12x+4)² and p²−6p+9

Answer:

Step-by-step explanation:

1. ok so you need to use Pythagoras which is a^2 + b^2 = c^2

substituting 16 and 12 into 'a' and 'b' you get 16^2 + 12^2 = c^2

256 + 144 = c^2

400 = c^2 (square root each side to get ride of the square)

c = 20cm

2. doing the same thing you get c = 22.36 in

3. again doing it you get c = 15Ft

Answer:

1.6 meters

Step-by-step explanation:

The distance between Shane and the bottom of the cliff is 7.8 meter while Naomi is standing 6.2 meters away from the bottom of the cliff.

As such, the distance between Shane and Naomi would be the difference between Shane's distance from the bottom of the cliff and Naomi's distance from the bottom of the cliff

= 7.8 - 6.2

= 1.6 meters

This is already in the nearest tenth

Answer:  6000ft2

Step-by-step explanation: Multiply 15*20*20 to find the area of a figure.

The total distance will Sara run in a 12-week training session is 1230 .

An arithmetic progression is a sequence of numbers or variables in which the difference between consecutive terms is the same. There can be an infinite number of terms in an AP.

The formula for finding the sum of first n terms of an AP given in the form of "a, a + d, a+2d, a+3d, ....., a+(n-1)d" is:

[tex]S _{n}[/tex]= [tex]\frac{n}{2}[/tex] [tex][2a + (n-1)d][/tex]

According to the question

Samantha is training to run a marathon.

She runs for five days each week

The first week she runs 4 km each day.  = 5 × 4 = 20

The second week, she runs 7 km each day. = 5 × 7 = 35

During each successive week , each day she runs 3 km farther than she ran the days of the previous week.

The third week, she runs 10 km each day. = 5 ×10 = 50

So on

Sara run in a 12-week training session

As this sequence is in AP  

First term (a) = 20

common difference (d) = 35 - 20

                                      = 15

Now,

Sum of 12 terms in AP

[tex]S _{n}[/tex]= [tex]\frac{n}{2}[/tex] × [2a + (n-1)d]

Substituting the values, a = 20, d = 15 and n = 12 in the above formula

[tex]S _{12}[/tex] = [tex]\frac{12}{2}[/tex] × [tex][2(20) + (12-1)15][/tex]

[tex]S _{12}[/tex] = [tex]6 [40 + (11)15}[/tex]

[tex]S _{12}[/tex] = [tex]6 [205][/tex]

[tex]S _{12}[/tex] = [tex]1,230[/tex]

Hence, the total distance will Sara run in a 12-week training session is 1230 .

Help verify values

Step-by-step explanation:

I basically help prove that the value fits and verifies that equation or inequality. By substituting a value for the variable within the equation or inequality and then solving it as a regular expression it should correctly output the same value on the other side of the equation or make the inequality true. For example, using the following inequality...

3x + 2 > 4

We can substitute the variable x for 2 and solve the inequality, if the inequality is true then we know that the value 2 is a correct and verified value.

(3*2) + 2 > 4

6 + 2 > 4

8 > 4  ... True

Answer:

The expression that represents Capri’s age is a + 4.

The expression that represents Portia’s age is a – 5.

Step-by-step explanation:

The expression that represents Capri's age is a + 4.

The expression that represents Portia's age is a -5.

To write an equation for this scenario, Capri's age needs to be equal to Portia’s age

The equation used to represent this scenario is a + a + 5 + 2 - 4 = 38.

Solving this equation will give Aziza's age.

Aziza'a age = a

Portia age = a - 5

Capri's age = 4 + a

a + a - 5 + 4 + a = 38
