Answer:
13x
Step-by-step explanation:
You add them all up since they're like terms and all have x
If the height of candle after 10 and 26 hours are 25 cm and 17 cm then the height of candle after 21 hours is 19.5 cm.
Given height of candle after 10 hours is 25 cm , height of candle after 26 hours is 17 cm.
We have to find the height of candle after 21 hours.
We have been given two points of linear function (10,25),(26,17).
We have to first form an equation which shows the height of candle after x hours.
let the hours be x and the height be y.
Equation from two points will be as under:
(y-25)=(17-25)/(26-10)* (x-10)
y-25=-8/16 *(x-10)
16(y-25)=-8(x-10)
16y-400=-8x+80
8x+16y=480
Now we have to put x=21 to find the height of candle after 21 years.
8*21+16y=480
168+16y=480
16y=480-168
16y=312
y=312/16
y=19.5
Hence the height of candle after 21 hours is 19.5 cm.

Answer:
-2.6, -2.16, 0.58, 0.8, 5.1
Explanation:
since negative numbers are less than 0. the bigger the negative the smaller the number is. once you pass negative aka on the right of 0 on a number line it would go normally
<u>positive</u>
0,1,2,3 <-----least to greatest
<u>negative</u>
-5, -4, -1, 0 <---- least to greatest
To find the area of a rhombus using diagonals, you must multiple the diagonals and divide then by 2. In this case 37 * 20 is 740. 740/2 is 370. 370 is your answer
Answer:
3(x + 1)(3 - x).
Step-by-step explanation:
(x + 3)^2 - 4x^2
Using the identity a^2 - b^2 = (a - b)(a + b), we have
(x + 3 - 2x)(x + 3 + 2x)
= (-x + 3)(3x + 3)
= 3(x + 1)(3 - x)
