<h2>Answer:</h2><h2>x^2+4 and X+2</h2>

Solution,

x^4-16

= (X^2)^2-(4)^2

Use the formula(a^2-b^2)

= (x^2+4)(x^2-4)

=(x^2+4)(x^2-2^2)

=(x^2+4)(X+2)(x-2)

Hope it helps

Good luck on your assignment

I need help please, i don’t not understand

Write in 0 and 0 at the top: this indicates that if there are zero pennies, the height of the tower is 0. This is the point (0,0). Another point is (4, 28): a tower of 28 pennies is 4 cm tall.

Find the slope of the line connecting (0,0) and (4,28).
4cm - 0 cm
m = ----------------- = (1/7) (cm/penny)
28 - 0

The equation we need, relating # of pennies to height of tower, is

t = (1/7) (cm/penny)x, where x is the # of pennies.

Thus, if x = 1, then t=1/7 cm

And, if x =15, then t = 15/7 cm

And so on.

Answer:

Step-by-step explanation:

The diagram is right angle triangle so we can use SOHCAHTOA

So in the diagram we have 62 degree opposite to x and the hypotenuse

Step 1

Sin62=x/16

Step 2

X=16sin62 by cross multiplication

Step 3

X=14.13

X=14

Heyy Answer please and explain

ludmilkaskok [199]

Answer: V=37.5 cm³

Step-by-step explanation:

Formula

V=(πr²h)/3

Given

r=5/2=2.5 cm

h=6 cm

Solve

V=(πr²h)/3

V=(π(2.5)²(6))/3

V=(π(6.25)(6))/3

V=37.5π/3

V=37.5(3)/3

V=37.5 cm³

Hope this helps!! :)
