Please HELP. 11x-2x+15=8+7+9x

Mathematics
1 answer:
ycow [4]4 years ago

<u>Hello!</u> ✌.ʕʘ‿ʘʔ.✌

Okay, let's start by first combining like terms on the left side of the equal sign. (づ。◕‿‿◕。)づ

11x - 2x = 9x

Now we have 9x + 15 = 8 + 7 + 9x! <em><u>Wow! </u></em>(ノ◕ヮ◕)ノ*:・゚✧

Now let's look at the right side.

8 + 7? That's easy! 15!

<u>So now we have...</u>

9x + 15 = 15 + 9x

Hmm... these equations are the same! So they will have infinite solutions! ᕙ(⇀‸↼‶)ᕗ

But let's keep going ( ̄。 ̄)~zzz

<u>Subtract 15 from both sides:</u>

<u>9x + 15 (-15) = 15 (-15) + 9x</u>

9x = 9x

<u>Divide both sides by 9x:</u>

9x/9x = 9x/9x

0 = 0

So the answer is....

<u><em>Drum roll please!!!</em></u>

<u><em>Dun dun dun</em></u>

<u><em></em></u>

<u><em>Infinite solutions! Yay! O(≧▽≦)O</em></u>

3x squared - 5x -7=0
Papessa [141]

The value of x is x=2.57338 and x=−0.906718

<h3>What is equation?</h3>

An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra.

Given:

3x²-5x-7=0

Using the discriminant method,

a = 3, b = -5, and c = -7

x= -b± √b²-4ac / 2a

x= 5 ± √25 + 84/ 6

x= 5± √ 109

Hence, x=2.57338 and x=−0.906718

Pleaseeeee help!!! I’ll give you best answer!!!!
MaRussiya [10]

Answer:

B) x = (-5 + √10)/3 and (-5 - √10)/3 is the answer.

Step-by-step explanation:

3x² + 10x + 5 = 0

a = 3

b = 10

c = 5

Finding the Discriminant (D),

D = b² - 4ac

D = 10² - 4 × 3 × 5

D = 100 - 60

D = 40

√D = 2√10

Using quadratic formula,

x = (-b ± √D)/2a

x = (-b + √D)/2a

x = (-10 + 2√10)/2 × 3

Taking out the common factor 2,

x = (-5 + √10)/3

Similarly,

x = (-b - √D)/2a

x = (-10 - 2√10)/2 × 3

x = (-5 - √10)/3

Radius of the circle is the length of rectangle divided by 2 (7cm)

Area of circle: pi*r²
Pi= 22/7

(22/7)*7²
=154

Since its a half circle, divide 154 by 2 =77

Area of rectangle:14*9=126

Subtract the circle from the rectangle: 126-77=49
