help finding the perimter of 78.4 inches whats the length of each side and show me how to work the promblem
LuckyWell [14K]
A square has four even sides and the perimeter is equal to the sum of all of the sides.
P=s+s+s+s=4s
So we can evaluate the equation for P and then solve for s.
78.4=4s \\  \frac{78.4}{4} =s \\ s=19.6in

Let f(x) = 5x3 + 3x2 – 3 and g(x) = x2 + X - 5, fin<br> 4) f(x) + g(x)
aleksley [76]

Answer:

f(x)+g(x)=5x^{3} +4x^{2}+x-8

Step-by-step explanation:

Given:

Two functions are given:

f(x)=5x^{3} +3x^{2} -3

g(x)=x^{2} +x-5

Find f(x)+g(x)

Solution:

f(x)+g(x)=(5x^{3} +3x^{2} -3)+(x^{2} +x-5)

f(x)+g(x)=5x^{3} +3x^{2} -3+x^{2} +x-5

f(x)+g(x)=5x^{3} +(3x^{2} +x^{2})+x-3-5

f(x)+g(x)=5x^{3} +4x^{2}+x-8

Therefore, the function of f(x)+g(x)=5x^{3} +4x^{2}+x-8
