Answer:

95 - 20\sqrt{15}

Step-by-step explanation:

(5\sqrt{3} - 2\sqrt{5} )²

= (5\sqrt{3} - 2\sqrt{5} )(5\sqrt{3} - 2\sqrt{5} )

each term in the second factor is multiplied by each term in the first factor, that is

5\sqrt{3} (5\sqrt{3} - 2\sqrt{5} ) - 2\sqrt{5} (5\sqrt{3} - 2\sqrt{5} ) ← distribute parenthesis

= 75 - 10\sqrt{15} - 10\sqrt{15} + 20 ← collect like terms

= 95 - 20\sqrt{15}

Answer:

95 - 20√15

Step-by-step explanation:

I assume the expression is (5√3 − 2√5)^2 (?).

(5√3 − 2√5)*(5√3 − 2√5)

25√3^2 - 20√15 + 4√5^2

25*3 - 20√15 +4*5

75 - 20√15 +20

95 - 20√15

Black_prince [1.1K]

Answer:

5.98

Step-by-step explanation:

2.99 * 1= 2.99

2.99+2.99= 5.98

First you had to multiply 2.99 by 1 because 100% in decimal is 1.

You get 2.99 and you add it to the original price.

And that is how you get 5.98

Write 3x+4y=12 in slope intercept form
cestrela7 [59]
Ok, let’s take it step by step.
In order to write an equation in slope intercept form, solve for y.
3x+4y=12
First, subtract 3x from both sides.
4y=-3x+12
Now, divide both sides by 4.
y=-3/4x+3.

So, 3x+4y=12 written in slope intercept form is y=-3/4x+3.
