5a+3b
5(2)+3(4)
10+12
22
(5+a)(3+b)
(5+2)(3+4)
(7)(7)
49
The order of the steps differ for the two expressions because for the first expression, you multiply 5a and 3b first. Then, you add them together. However, for the second expression, you add what's inside the parenthesis first then multiply them. So, the order of the steps is the opposite of the other expression.
Step-by-step explanation:
do 590 divided by 90 if that doesn't work multiply it
Answer:

Step-by-step explanation:
We want to to rewrite

Use difference of two squares to get:

This implies that:


This finally simplifies to:

Therefore the required product is

The answer for the blank space is 21.8
solving a linear equation we conclude that the value of x must be 6.
<h3>
How to find the value of x?</h3>
On the statement we have the relations:
AB = BC
BC = CD
For the transitive property, then we have that:
AB = CD
Replacing the equations in the image, we get:
2x + 1 = 4x - 11
Solving this linear equation for x we get:
1 + 11 = 4x - 2x
12 = 2x
12/2 = x
6 = x
So yes, solving that linear equation we conclude that the value of x must be 6.
