From the image, we can see the amount of water in Liters are in the beaker.
The beaker is marked with numbers that are skip counting by 10. (10,20,30) so on. There are 4 ticks below the 10, 5 if you count the 10.
So that means 10/5 = 2 L per tick.
The water goes above the 30 mark and under the 40 mark, which means it's somewhere in the 30's.
Since each tick is 2 L, and the water goes to the third tick:
2L + 2L + 2L = 6L.
Add 6L to 30: 30+ 6L = 36L
Answer:
Step-by-step explanation:
To explain how to approach this question, I am going to place letters in the blank spaces:
First, compare the <u>coefficients</u> of the x² terms on both sides of the equation:
Therefore, we need to choose any two numbers in place of a and d whose difference is -5:
⇒ a = 2 and d = 7 as 2 - 7 = -5.
Similarly, upon comparing the <u>coefficients</u> of the x terms, we can see that there is no x term on the right side of the equation. Therefore, we need to choose numbers in place of b and e for which the difference is zero. So b and e should be the <u>same number</u>:
⇒ b = 2 and e = 2 as 2 - 2 = 0.
Finally, compare the constant term on both sides of the equation:
Therefore, we need to choose any two numbers in place of c and f whose difference is -14:
⇒ c = 1 and f = 15 as 1 - 15 = -14.
Plug in the numbers in place of the letters on the left side of the equation:
<u>Check</u>
Remove the brackets:
Collect like terms:
Combine like terms:
Hence proving that the left and right sides of the equation are the same.
Answer:
what one?
Step-by-step explanation:
Mean of wat? And we need to see a picture of the equation
F(x) = 2x² + 7x - 5
g(x) = -8x² - 3x + 5
g(x) + f(x) = -8x² - 3x + 5 + 2x² + 7x - 5 = - 6x² + 4x
Answer: -6x² + 4x
