In step three the prblem was incorrect. this is because you have to add four from both sides leading to 8x=20+3x then you have to subtract 3x which is 5x=20. divinding both sides by 5 is:
X=4
Answer:
<h2>3x³ + 5</h2>
Step-by-step explanation:
( 4x - 2x³ ) + ( 5x³ - 4x + 5)
<u>Remove the parenthesis</u>
That's
4x - 2x³ + 5x³ - 4x + 5
<u>Group like terms</u>
We have
5x³ - 2x³ + 4x - 4x + 5
We have the final answer as
<h3>3x³ + 5</h3>
Hope this helps you
In 60 minutes, the machine can sew 300 buttons. The machine sews 5 buttons a minute. 60 x 5 = 300
1. The diagonal is the hypotenuse so,
√[12² + 12²] = 16.97
2. The same process is done
51.96
3. Again, use the Pythagorean theorem
35.78
4. The perimeter is 44, so the length of a side is 11, the diagonal is
15.57
5. The diagonal is 20, the formula is
d =s√2
where d is the diagonal and s is the side
s = 14.14
Answer:
They would be 132km apart
Step-by-step explanation:
In order to solve this we need to set up a proportion. To make that easier, let's first change the fractions into decimals.
2 1/2 = 2.5
5 1/2 = 5.5
Now we can put the scale in the right side fraction and the distance in the left.
2.5cm/60km = 5.5cm/xkm
Now cross multiply to solve
60 * 5.5 = 2.5 * x
330 = 2.5x
132 = x
