De las soluciones de la siguiente ecuación: x2 + 8x − 30 = 18? Cual es el numero de mayor valor Entre.

vekshin1

Answer:

The correct answer is "x = 4" and "x = -12".

Step-by-step explanation:

The given equation is:

⇒ $x^2+8x-30=18$

On subtracting "18" from both sides, we get

⇒ $x^2+8x-30-18=18-18$

⇒ $x^2+8x-48=0$

On applying factorization, we get

⇒ $x^2+12x-4x-48=0$

On taking common, we get

⇒ $x(x+12)-4(x+12)=0$

⇒ $(x-4)(x+12)=0$

⇒ $x-4=0$

$x=4$

or,

⇒ $x+12=0$

$x=-12$

after elsa backed muffins, her brother ate 4 of them, he ate 2/5 of all the muffins, how many muffins did elsa bake?

kondor19780726 [428]

If he ate 4 of them, but it means he ate 2/5 muffins,
4 muffins = 2/5 muffins
You substitute x muffins for how much muffins she baked in all -
2/5* x muffins = 4
2/5 multiply by 2/5 to cross it out. Do the same to the other side.
x= 4 *5/2
x = 10 muffins
So there were 10 muffins in all
