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:

7

Answer:

In Fraction  = 10/100  simplified =  1/10

Decimal = 0.1

Percentage = 10%

Step-by-step explanation:

We add all marbles = 5+ 3+ 2 = 10

Event 1 = Red  = 5/10

Event 2 = Green = 2/10

We follow this path and multiply =  2 x 5 /  10 x 10 =  10/100 = 1/10

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:

For this case, the surface area of the cylinder is given by:

A = 2 * pi * r * h + 2 * pi * r ^ 2

Where.

r: cylinder radius

h: cylinder height

Substituting values we have:

A = 2 * 3.14 * 5 * (2 * 5) + 2 * 3.14 * 5 ^ 2

A = 471

Answer:

The total surface area of the cylinder is:

A = 471

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

Arnav needs to sell more than 8 boxes of cookies to reach his goal of making more than $30. Since the number of boxes must be a whole number, Arnav would need to sell at least 9 boxes of cookies to achieve his goal.

To determine how many boxes of cookies Arnav needs to sell to reach his goal of making more than $30, we can set up an inequality based on the selling price of each box.

Let's represent the number of boxes he sells as "x". Since each box is sold for $3.75, the total amount of money he will earn from selling "x" boxes is 3.75x.

To reach his goal of making more than $30, we can write the following inequality:

3.75x > 30

To solve for "x", we divide both sides of the inequality by 3.75:

x > 30 / 3.75

Simplifying the right side of the inequality, we get:

x > 8

To fulfil his objective of earning more than $30, Arnav must sell more than 8 boxes of cookies. Arnav would need to sell at least 9 boxes of cookies in order to reach his objective because the number of boxes must be a whole number.
