Answer:

No solutions.

Step-by-step explanation:

We have been given an equation 4n-9 =2 (5+2n). We are asked to find the solution of our given equation.

First of all, we will use distributive property on right side of equation as:

4n-9 =10+4n

We can see that both lines are parallel as both lines have same slope and different y-intercepts.

We also know that two parallel lines never intersect, therefore, there is no solution for the given equation.

We can also try to solve our equation as:

4n-4n-9 =10+4n-4n

-9=10

Since both sides of equation are not equal, so there is no solution for our given equation.

What is the gradient of the graph shown? <br> Give your answer in its simplest form.
Ede4ka [16]

Answer:

The gradient is m=1/3

Step-by-step explanation:

The gradient, known as the slope, is the rate of change, defined as the change in y divided by the change in x. In this case, we will select two points from the line and calculate the slope from there. I selected (0,3) and (3,4) to demonstrate:

Slope=m=(y2-y1)/(x2-x1)=(4-3)/(3-0)=1/3

Therefore, the gradient/slope is 1/3.

A paint can is a cylinder
surface area of a cylinder = <span>2(3.14) *</span><span> r^</span>2<span> + 2(3.14)</span><span> * r * h
SA = 2(3.14) * 8.5^2 + 2(3.14) * 8.5 * 24
SA = 6.28 + 72.25 + 6.28 * 8.5 * 24

Which expression is equivalent to the given expression using the commutative property of addition.​
9966 [12]

The given question is wrong.

Question:

Which expression is equivalent to the given expression using commutative property of addition? 2(x + b) + 3(xa).

Answer:

Option C:

3(xa) + 2(x + b)

Solution:

Given expression is 2(x + b) + 3(xa).

To find the equivalent expression using commutative property of addition.

Let us first define the commutative property of addition.

a + b = b + a

You can add in any order.

Now, write the given expression using commutative property.

2(x + b) + 3(xa) = 3(xa) + 2(x + b)

Option C is the correct answer.

Hence 3(xa) + 2(x + b) equivalent expression using commutative property of addition.
