I'll do it for you. You put a 1 under the 4 to make it a fraction, then you multiply and after you divide

What i like to do is turn the 4 2/3 into a improper fraction which will be 14/3. When you did that it will make it easier for you to multiple it. And you know the whole 4, i put a denominator of 1 because 4/1 = 4 (it'll just make it easier throughout your work.)

4 14
-- x -- =
1 3

4 x 14 = 56
1 x 3 = 3

The answer is 56/3 = 18 2/3

Find the value of in the triangle shown below 9, 7, and x around the triangle

enot [183]

Answer:

5.66 units

Step-by-step explanation:

A's per our discussion, x is a leg of right triangle.

Therefore, by Pythagoras theorem:

$x = \sqrt{ {9}^{2} - {7}^{2} } \\ = \sqrt{81 - 49} \\ = \sqrt{32}$

$x = \sqrt{ {16}^{2} - {12}^{2} } \\ = \sqrt{256 - 144} \\ = \sqrt{112}$

Pleaseeee help meee i dont understand

prohojiy [21]

-(5y) - y = 18
-6y = 18
y = -3
x = 5(-3)
x = -15
(-15, -3)

5x + 4(-7x - 3) = -35
5x -28x -12 = -35
-23x = -23
x = 1
y = -7(1) - 3
y = -10
(1,-10)

Point slope equations

Sholpan [36]

Answer:

The point slope equation is: y - y1 = m (x - x1)

m = slope

Step-by-step explanation:

To use this equation, you need to know:

- one point on the line

- the slope of the line

First:

(x1,y1) = a known point on the line

m = the slope

(x,y) = any other point on the line

Now:

we plug the numbers into the equation to get y - y1 = m (x - x1)

Then:

you solve the equation

How do you solve this problem? (x+3) cubed

Lubov Fominskaja [6]

You would expand becausee it isn't equal to anything

(x+3)^3=(x+3)(x+3)(x+3)
we can use binomial theorem or pascal's triangle
anyway, pascal's triangle is more practicl for this one

so
for the 3rd power
$(a+b)^3=1a^3+3a^2b^1+3a^1b^2+1b^3$

a=x
b=3

$(x+3)^3=1x^3+3x^2(3^1)+3x^1(3)^2+1(3)^3$ =
$x^3+9x^2+27x+27$
