Take out a GCF (greatest common factor, which is 3x) factor what is left, (x^2 - 4)

Please respond if you understand, or if you need more help!

ab-ac=a(b-c)

a=GCF

so factor

3x^3=3*x*x*x
12x=2*2*3*x
gcf=3*x=3x

3x(x^2)-3x(4)=3x(x^2-4)
we can also factor the inner further
remember that a^2-b^2=(a+b)(a-b)
so
(x^2-4)=x^2-2^2=(x+2)(x-2)

fully factored is
3x(x+2)(x-2)

What is the value of x?<br><br> Enter your answer in the box.
ehidna [41]

Answer:

25

Step-by-step explanation:

c^2=a^2+b^2

where c = hypotenuse

so, x^2 = 24^2+7^2

x^2 = 576 + 49

x^2 = 625

x = square root of 625

x = 25

Find the length of diagonal HJ. Round to the nearest hundredth.
Alisiya [41]

Answer:

The length of the diagonal HJ is 10.82 units

Step-by-step explanation:

* Lets revise the rule of the distance between two points

- d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}, where

 (x_{1},y_{1}) and (x_{2},y_{2}) are the two points

* Lets use this rule to find the length of the diagonal HJ

∵ The coordinates of point H are (-4 , 3)

∵ The coordinates of point J are (5 , -3)

∴ x_{1}=-4 and x_{2}=5

∴ y_{1}=3 and y_{2}=-3

- Lets find the length of the diagonal HJ by using the rule above

∴ HJ = \sqrt{(5-(-4))^{2}+(-3-3)^{2}}=\sqrt{(5+4)^{2}+(-6)^{2}}

∴ HJ = \sqrt{(9)^{2}+36}=\sqrt{81+36}=\sqrt{117}=10.81665

∴ HJ = 10.82

* The length of the diagonal HJ is 10.82 units

If the reciprocal of the number $X$ equals $\frac{2}{7}$, what is $5$ divided by $X$?
grigory [225]
U can find the reciprocal of a number by flipping the number.
example : the reciprocal of 1/5 is 5/1....the reciprocal of 2/3 = 3/2.

the reciprocal of x = 2/7.....that means x = 7/2

5 / (7/2) = when dividing fractions, flip what u r dividing by, then  multiply
5 * 2/7 =
10/7 or 1 3/7 <==
