mart [117]
(7/2b - 3) - (8 + 6b)
= 7/2b - 3 - 8 - 6b
= 7/2b - 6b - 11
= -5/2b - 11

In short, Your Answer would be Option A

What is the factorization of 121b^4 − 49?
lora16 [44]

Answer:

(11b^2 + 7) (11b^2 - 7)

Explanation:

Since both terms are perfect squares, factor using the difference of squares formula,  a^2 - b^2 = (a + b) (a - b) where a = 121b^4 and b = 49

Flura [38]

Answer:  The answers are given below.


Step-by-step explanation:  Given that we are assembling pieces of an iron gate to complete a fence. The finished gate will look like the figure as given in the question.

Part 1: We can clearly see in the picture given that pieces 1 and 2 are placed at an angle of 90° to each other. Therefore, the pieces 1 and 2 are perpendicular to each other.

Part 2: Also, it can be seen that in the centre of the gate, the rectangular sections 5 and 6 are placed at an angle of 0° to each other. Therefore, sections 5 and 6 are parallel to each other.

Thus, 1 and 2 are perpendicular;  5 and 6 are parallel to each other.

<h3>What are linear equations?</h3>

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

<h3>How to determine the graph of the points on the coordinate plane.?</h3>

A system of linear equations is a collection of at least two linear equations.

In this case, the points are given as

(7, 3) and (1, 5)

The point (7, 3) means that:

x = 7 and y = 3

i.e. the point is located 7 units to the right of the origin and 3 units up the origin

Similarly,

The point (1, 5) means that:

x = 1 and y = 5

i.e. the point is located 1 unit to the right of the origin and % units up the origin

Next, we plot the points on the coordinate plane.

See attachment of the graph of the points on the coordinate plane.
