Answer:

x = ± 2

Step-by-step explanation:

Given

x² + 5 = 3x² - 3 ( subtract x² + 5 from both sides )

0 = 2x² - 8 ( add 8 to both sides )

8 = 2x² ( divide both sides by 2 )

4 = x² ( take the square root of both sides )

x = ± $\sqrt{4}$ = ± 2

The icecream parlor has 30 flavors, but for the last week they have only had 25 flavors. Find the percent of change. Tell if it

irina [24]

Answer:

The percent of change is 20%.

And it is increased by last month.

Step-by-step explanation:

Given:

The ice cream parlor has 30 flavors, but for the last week they have only had 25 flavors.

Now, to find the percent of change.

Flavors ice cream parlor has = 30.

Flavors last week they had = 25.

So, the flavors increased from last week by:

$30-25=5\ flavors.$

Now, to get the percent of change:

$\frac{5}{25} \times 100$

$=\frac{500}{25}$

$=20\%.$

Thus, the percent of change is 20%.

The flavor is increased by last month.

Therefore, the percent of change is 20%.

And it is increased by last month.

avanturin [10]

Answer:

x=8,x=-3 is the answer.

Step-by-step explanation:

solution;

here,

$x^{2}-5x-24=0\\x^{2} -8x+3x-24=0\\x(x-8)+3(x-8)=0\\(x+3)(x-8)=0\\$

$x+3=0.....I\\x-8=0......II\\$

Solving equation I

x+3=0

x=-3

Solving equation II

x-8=0

x=8
