-9 -4x = 7

add 9 to both sides in order to isolate the x

-4x = 16

divide by -4

x = -4

Hey there! :)

-9 - 4x = 7 ; find x.

In order to find the value of x, we must isolate the variable. This simply means that we need to get x alone on its own side of the equal sign.

We can start by adding 9 to both sides.

-9 + 9 - 4x = 7 + 9

Simplify!

-4x = 16

Then, divide both sides by -4.

-4x ÷ -4 = 16 ÷ -4

Simplify.

x = -4

Your final answer is : x = -4

Hope this helped! :)

Find the area of the circle. Leave your answer in terms of Pi. Diameter is 14 ft.
QveST [7]

Answer:

The area of the circle is 49\pi\ ft^{2}

Step-by-step explanation:

we know that

The area of a circle is equal to

A=\pi r^{2}

we have

r=14/2=7\ ft -----> the radius is half the diameter

substitute the value

A=\pi (7)^{2}

A=49\pi\ ft^{2}

What are 3 consecutive integers whose product is -120
iren2701 [21]
Consecutive integers are 1 apart
x,x+1,x+2
(x)(x+1)(x+2)=-120
x^3+3x^2+3x=-120
add 120 to both sides
x^3+3x^2+3x+120=0
factor
(x+6)(x^2-3x+20)=0
set each to zero

x+6=0
x=-6

x^2-3x+20=0
will yeild non-real result, discard
x=-6
x+1=-5
x+2=-4
the numbers are -4,-5,-6



use trial and error and logic
factor 120
120=2*2*2*3*5
how can we rearange these numbers in (x)(y)(z) format such that they multiply to 120?
obviously, the 5 has to stay since 2*5=10 which is out of range
so 2*2*2*3 has to arrange to get 3,4 or 4, 6 or 6,7
obviously, 7 cannot happen since it is prime
3 and 4 results in in 12, but 2*2*2*3=24
therfor answer is 4 and 6
they are all negative since negaive cancel except 1

the numbers are -4,-5,-6
