Simplify 8(x+3)^2/2(x+3)

Answers

The simplification of the given expression [8(x+3)²]/[2(x+3)] is 4(x + 3).

What is an expression?

An expression is a combination of some mathematical symbol such that an arithmetic operator and variable such that are all constrained and create an equation.

In other meaning, expression is beneficial to determine the end or root value of constraint.

As per the given expression,

[8(x+3)²]/[2(x+3)]

⇒ 8/2 × (x+3)²/(x+3)

⇒ 4(x+3)

Hence "The simplification of the given expression [8(x+3)²]/[2(x+3)] is 4(x + 3)".

If the price of an item is increased by 12%, the increase in the price is sh.90. Find the new price of the item.

Answers

Hello!

Answer:

Hence,the new price of the item is 840 shillings.

Answer:

sh.840

Step-by-step explanation:

Let x = original price.

12% of x = 90

0.12x = 90

x = 90/0.12

x = 750

The original price was sh.750

The new price is 750 + 90 = 840

Answer: sh.840

Equation of perpendicular line:

Equation of parallel line:

Answers

1)Parallel means they have to have the same slope. Since our equation is y=2/3x+1, a line parallel to that would be(using out points) -5=2/3(-4)+b.

To find the y-intercept, solve for "b".

b=-7/3

Our equation would then be y=2/3x-7/3

2)Perpendicular lines have opposite-reciprocal slopes. our previous equation was y=2/3x+1, so our new equation would be -5=-3/2(-4)+b. Now lets solve for b.

b=-11

So our perpendicular equation would be y=-3/2x-11
