You are ordering pizzas for a birthday party and getting them delivered to your house. You order 12 pepperoni pizzas, 8 cheese p
krok68 [10]

Let

x-------> the cost of each  pepperoni pizza

y-------> the cost of each  cheese pizza

z-------> the cost of each  Hawaiian pizza

we know that

12x+8y+4z+5.50=184.54 ------> equation A

y=x -----> equation B

z=x -----> equation C

Substitute equation B and equation C in equation A

12x+8x+4x+5.50=184.54

solve for x

24x=184.54-5.50

x=179/24

x=\$7.46

therefore

<u>the answer is</u>

\$7.46

Find the surface area of this cube. Be sure to include the correct unit in your answer.
NikAS [45]
Are the dimensions 8yd x 8yd x 8yd? If so this is how you do:

First calculate the area or one side. Then multiply it by 6 as all the sides of the cube have the same area.

Side area = 8yd x 8yd = 64yd^2

Surface area = 6 x 64yd^2 = 384yd^2

Y=sech(tan‐¹x) find the derivative ​
Klio2033 [76]

Recall that

d/dx sech(x) = - sech(x) tanh(x)

d/dx tan⁻¹(x) = 1/(1 + x²)

Then by the chain rule,

dy/dx = - sech(x) tanh(x) / (1 + x²)
