If f(x)=x^2-5 and g(x)=6x then g(f(x)) is equal to

Answers

Answer 1

Answer: g(x) = 6x

g(f(x))
= 6((x^2) - 5)
= (6x^2) - 30

so its equal to
(6x^2) - 30

Answer 2

Answer: Plug f(x) as x in g(x) and you get 6(x^2-5), which is g(f(x)) = 6x^2-30.

Simplify the expression

Answers

Answer:

The simplified form of given expression $\frac{15xy}{5x^{(1)/(2)}y^2}$ is $\frac{3x^{(1)/(2)}}{y}$

Step-by-step explanation:

Given: Expression $\frac{15xy}{5x^{(1)/(2)}y^2}$

We have to write the given expression in simplified form,

Consider the given expression $\frac{15xy}{5x^{(1)/(2)}y^2}$

Divide the numbers $(15)/(5)=3$

we get,

$=\frac{3xy}{y^2x^{(1)/(2)}}$

Apply exponent rule , $(x^a)/(x^b)\:=\:x^(a-b)$

$\frac{x}{x^{(1)/(2)}}=x^{1-(1)/(2)}=x^{(1)/(2)}$

we get,

$=\frac{3yx^{(1)/(2)}}{y^2}$

Cancel y term, we have,

$=\frac{3x^{(1)/(2)}}{y}$

Thus, The simplified form of given expression $\frac{15xy}{5x^{(1)/(2)}y^2}$ is $\frac{3x^{(1)/(2)}}{y}$

Answer:

$3x^{(1)/(2)}y^(-1)$

Step-by-step explanation:

The given expression is:

$\frac{15xy}{5x^{(1)/(2)}y^2}$

We have to simplify the above given expression.Thus,

Firstly, divide the constant terms, we get

$(15)/(5)=3$

Now, applying the exponent law, that is $(x^a)/(x^b)=x^(a-b)$ , we have

$\frac{xy}{x^{(1)/(2)}y^2}=x^{1-(1)/(2)}y^(1-2)=x^{(1)/(2)}y^(-1)$

Thus, the simplified form of the above given equation is:

$3x^{(1)/(2)}y^(-1)$

Solve: y = -7(-13).

the length of a rectangle is 9 centimeters more than the width. the area is 112 square centimeters. find the length and width of the rectangle

Answers

l = w + 9

lw = 112

Substitute l = w + 9 into the second equation

(w + 9)(w) = 112

w^2 + 9w - 112 = 0
(w+16)(w-7) = 0

w = -16
or
w = 7

we have to take the positive value, so w = 7

l = w + 9
l = 7 + 9
l = 16

The length is 16, and the width is 7

here,
let width(b)be x then,
length (l)=9cm+x
area =112 sq cm
now,
area of rectangle=l*b
or, 112=(9+x)x
or, 112=9x+x^2
or, 0=x^2+9x-112
or, 0=x^2+(16-7)x-112
or, 0=x^2+16x-7x-112
or, 0=x(x+16)-7(x+16)
or, 0=(x-7)(x+16)
either,
0=x-7
or,7=x
x=7cm
Or,
0=x+16
or, -16=x
x= -16[impossible,as distance is never negative] so,
x=7cm
therefore,length = 7cm + 9 cm = 16cm and width = 7cm.

Answer:

whats the question?

Step-by-step explanation:

Answer:

n=4

Step-by-step explanation:

To write this equation, we know that five more than n equals 5. The word "more" implies we are adding. So we can write n+5=9 as our equation. We need to isolate the variable, so we get only n on one side. So we subtract 5 from each side to isolate. 9-5=4. So our new equation is n=4. This is also our answer!
