if the length of a rectangle is increased by 30 percentage and the width of the same rectangle is decreased by 30 what is the af
LUCKY_DIMON [66]

Answer:

The area will decrease by 9%.

Step-by-step explanation:

The area of a rectange is given by the formula below.

\boxed{\text{Area of rectangle}= \text{length}×\text{width}}

Let the original length and width of the rectangle be L and W respectively.

Start by finding the original area:

<u>Original </u><u>dimensions</u>

Length= L= 100%L

Width= W= 100%W

Original area= LW

Let's find the dimensions of the new rectangle in terms of L and W.

<u>New dimensions </u>

Length= (100% +30%)L= 130%L

Width= (100%-30%)W= 70%W

New area

=  \frac{130}{100} L  \times \frac{70}{100} W

=  \frac{91}{100} LW

= 91% LW

Comparing the new area with the original area:

100% LW- 91% LW= 9% LW

∴ The area will decrease by 9%.

*Note that percentage is equivalent to dividing a number by 100.

Given the function f(x)=-2x^2+6x ,then what is f(x)=−3 as a simplified polynomial?
GenaCL600 [577]

The given function, f(x) = -3, written as a simplified polynomial is 2x² - 6x- 3 = 0

<h3>Simplified Polynomials</h3>

From the question, we are to determine f(x) = -3 as a simplified polynomial

From the given information,  we have that

f(x) = -2x^2 + 6x

Rewrite the the given equation properly.

Rewriting, we get

f(x) = -2x² + 6x

Also, from the given information

We have that

f(x) = -3

Thus, we can write that

- 3 = -2x² + 6x

Writing the above equation as a simplified polynomial, we get

- 3 = -2x² + 6x

2x² - 6x- 3 = 0

Hence, the given function, f(x) = -3, written as a simplified polynomial is 2x² - 6x- 3 = 0

Select all the pairs of equivalent expressions.
iren2701 [21]

Answer:

\huge\boxed{(3^4)^4=3^8\cdot3^8}\\\boxed{4^3\cdot5^3=20^3}\\\boxed{(4^3)^3=4^3\cdot4^3\cdo4^3}

Step-by-step explanation:

a^n\cdot a^n=a^{n+m}\\\\(a^n)^m=a^{n\cdot m}\\\\(a\cdot b)^n=a^n\cdot b^n\\=====================

(4^3)^3=4^{3\cdot3}=4^9\\4^3\cdot4^3=4^{3+3}=4^6\\\\4^9\neq4^6\to(4^3)^3\neq4^3\cdot4^3\\==================

(3^4)^4=3^{4\cdot4}=3^{16}\\3^8\cdot3^8=3^{8+8}=3^{16}\\\\(3^4)^4=3^8\cdot3^8\\================

6^4\cdot3^4=(6\cdot3)^4=18^4\\\\18^4\neq18^8\to6^4\cdot3^4\neq18^8\\=================

4^3\cdot5^3=(4\cdot5)^3=20^3\\\\4^3\cdot5^3=20^3\\=================

(4^3)^3=4^{3\cdot3}=4^9\\4^3\cdot4^3\cdot4^3=4^{3+3+3}=4^9\\\\(4^3)^3=4^3\cdot4^3\cdot4^3
