Answer:
1) Isosceles
2) Scalene
3) Scalene
Step-by-step explanation:
The 1st choice is isosceles because 2 side lengths are equal.
The 2nd and 3rd choice are scalene because none of the sides equal the other sides.
Answer:
There are 0.70km in 765 yards.
Step-by-step explanation:
This is a problem of conversion of units, that can be solved by multiple rule of three's.
The first step is converting 765 yards to feet. We have that each yard has 3 feet, so
1 yard- 3 feet
765 yards - x feet
x = 765*3
x = 2295
So, in 765 yards there are 2295 feet.
Now, we have to convert 2295 feet to miles. Each mile has 5280 feet, so:
1 miles - 5280 feet
x miles - 2295 feet
5280x = 2295
x = 0.435 miles
So, in 765 yards there are 2295 feet which is 0.435 miles
Now, the final step is converting from miles to kilometers. Each km has 0.621 miles, so:
1km - 0.621 miles
xkm - 0.435 miles
0.621x = 0.435
x = 0.70km
So, there are 0.70km in 765 yards.
Hello,
c1=10.9 (in) A1=392.4 (in²)
c2=21.8 (cm) =21.8/2.54 (in)
k=c2/c1=(21.8/(2.54*10.9)=2/2.54
A2=(2/2.54)²*392.4=243,28848...≈243.29 (in²)
Answer: 15x² + 2x + 4
x = -2/3, 0, 1/2
Step-by-step explanation:
5x(3x + 2) - 4(2x - 1)
First, distribute:
15x² + 10x - 8x + 4
Combine like terms:
15x² + 2x + 4
This is your polynomial!
If you needed to solve for x, take your original factored polynomial and set each term equal to 0:
5x(3x + 2) - 4(2x - 1)
5x = 0
x = 0
3x + 2 = 0
3x = -2
x = -2/3
-4 = 0
No solution
2x - 1 = 0
2x = 1
x = 1/2
x = -2/3, 0, 1/2
Hope this helps!
