Answer:
2+3=5
Step-by-step explanation:
100x + 300 = 500
100x = 500 - 300
100× = 200
100x/100 = 200/100
therefore ^x = 2
x + 3 = 5
2 + 3 = 5
Answer:
The discrimant of this equation is 144.
Step-by-step explanation:
First you have to move all the variables to one side to make the equation/expression into 0 by substracting 8x² to both sides :
9x² + 14x + 13 = 8x²
9x² + 14x + 13 - 8x² = 8x² - 8x²
x² + 14x + 13 = 0
It is given that the formula of discriminant is, D = b² - 4ac where a&b&c represent the number of the equation, ax²+bx+c = 0 :
x² + 14x + 13 = 0
D = b² - 4ac
= 14² - 4(1)(13)
= 196 - 52
= 144
Answer:
<u>240cm³</u>
Step-by-step explanation:
To find our answer we will <u>multiply</u> the <em>volume, width, and height</em>.
4 · 20 · 3 = 240. Therefore, <u>240cm³ is our answer.</u>
