Answer:
P = 20 cm
Step-by-step explanation:
The appropriate formula is P = 2W + 2L.
Here that comes to P = 2(6 cm) + 2(4 cm) = 20 cm
Answer:
50y^4x/49
Step-by-step explanation:
y^3/98
((100* y^3/98 * x) * y
2.1 y^3 * y^1=y^(3+1)=y^4
Answer:
y=11
Step-by-step explanation:
Solve the system by substitution by setting the equations equal to each other.
y = 5x+6
y = x+10
It becomes 5x+6 = x+10. Solve for x using inverse operations.
5x+6 = x+10
4x+6 = 10
4x = 4
x=1
Substitute x=1 into one equation to find y.
y = x+10
y = 1 +10
y=11
Subtract 14 from 15.96 to find the increase.
15.96 - 14 = 1.96
Divide 1.96 by 14.
1.96 / 14 = 0.14
In percents that is 14%.
This is an increase of 14%.
Hope this helps!
