Answer:

A perfect square trinomial is the square of a binomial. It follows a pattern when it is factored, so that the first and last terms are perfect squares of monomials and the middle term is twice their product

PLEASE HELP!!! WILL MARK AS BRAINLEIST <br> Which ones are linear and nonlinear<br> Picture bellow

OlgaM077 [116]

Linear equations are:

$y=x+5$

$5x+5y=25$

Non-linear equations are:

$y = 2x^3$

$y=x^2-3$

$y=\frac{x^2}{2}$

Step-by-step explanation:

Lets define linear and non-linear first.

Linear equation is that equation whose degree is one. Degree is the highest power of a variable in an expression or equation.

Similarly, an equation with degree greater than 2 are called non-linear equation

In the given equations,

$y = 2x^3$ => Degree: 3

$y=x+5$ => Degree: 1

$y=x^2-3$ => Degree: 2

$5x+5y=25$ => Degree:1

$y=\frac{x^2}{2}$ => Degree:2

Hence,

Linear equations are:

$y=x+5$

$5x+5y=25$

Non-linear equations are:

$y = 2x^3$

$y=x^2-3$

$y=\frac{x^2}{2}$

I don't know what you mean by "Broken apart," but I'll do my best...

20 x 90 = 1800

9 x 7 = 63

1800 + 63 = 1863

I hope this helped you! :)

Lynn measured the length of her front yard by counting her strides. The yard measured 18.5 feet long. Emily measured the same ya

Answer:

8.11%

Step-by-step explanation:

We need to find the percentage error. We can follow the formula shown below:

$PE=\frac{New-Orig}{Orig}*100$

Where

PE is the Percentage Error

New is the newest measure (given as 20 feet)

Orig is the original, or first, measure (given as 18.5)

Substituting and finding the PE:

$PE=\frac{New-Orig}{Orig}*100\\PE=\frac{20-18.5}{18.5}*100\\PE=\frac{1.5}{18.5}*100\\PE=8.11$

Tagging the percentage , percent error is about 8.11%
