Answer:

\text{The solution is }x=5\pm \sqrt{35}    

Step-by-step explanation:

Given the equation

x^2-10x+25=35

we have to solve the above equation for x

x^2-10x+25=35

Subtracting 35 from both sides, we get

x^2-10x-10=0

\text{Comparing above equation with }ax^2+bx+c=0

a=1, b=-10, c=-10

By quadratic formula, the solution is

x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

x=\frac{-(-10)\pm \sqrt{(-10)^2-4(1)(-10)}}{2(1)}

x=\frac{10\pm \sqrt{100+40}}{2}

x=\frac{10 \pm \sqrt{140}}{2}

x=\frac{10 \pm 2\sqrt{35}}{2}

x=5\pm \sqrt{35}

which is required solution.

The left side of this equation is already a perfect square:    <span>x^2-10x+25=35.

Rewriting it, we get (x-5)^2 = 35.

Taking the sqrt of both sides,    x-5 = sqrt(35).

Solving for x:    x = 5 plus or minus sqrt(35)    (answers)</span>

During normal breathing, about 12% of the air in the
nekit [7.7K]

The original air present after 8 breaths will be equal to 179.81 ml.

<h3>What is an equation?</h3>

The equation in mathematics is the relationship between the variables and the number and establishes the relationship between the two or more variables.

It is given in the question that:-

During normal breathing, about 12% of the air in the lungs is replaced after one breath

If the initial amount of air in the lungs is 500 mL

how much of the original air is present after 8 breaths?

The calculation for the eduction of the air will be done by the following equation:-

\rm =Volume \ present\times (0.88)^n\\\\\\= 500\times (0.88)^8

=179.88 ml

Hence original air present after 8 breaths will be equal to 179.81 ml.

SOMEONE PLEASE HELP ME WITH THIS AND EXPLAIN EACH ONE AND HOW YOU DID IT PLEASE MY TEACHER SUCK AND ILL GIVE YOU BRAINLY IF U GE
valentinak56 [21]

Answer:

a)

d)

Step-by-step explanation:

It's easiest to reduce each statement to its simplest form for comparison

Our test statement can be reduced by combining like terms

16x - 12 -24x + 4 = -8x - 8

this becomes our new gold standard

a) 4 + 16x - 12(1 + 2x)

apply the distributive property by multiplying terms in parenthesis by -12

4 + 16x - 12 - 24x

combine terms

-8x - 8     Yeaah, We have a winner as it exactly matches our gold standard.

b) 40x - 16 is already in simplest terms and does NOT match the gold standard.

c) 16x - 24x - 4 + 12

has the same cardinal values as the original, but differing signs, reducing gives -8x + 8

Not quite the same as a plus sign occurs where a negative exists in our gold standard.

d) -8x - 8  is already in simplest terms and exactly matches our gold standard. Yeah!

e) 10(1.6x - 1.2 - 2.4x + 4)

apply distributive property by multiplying each term in parenthesis by 10

16x - 12 - 24x + 40

combine like terms

-8x + 28 does NOT match our gold standard
