Z = 2
1. distribute the 2 first by multiplying it by 6z and 2

2. Cancel out the 4 by subtracting 4 from both sides

3. Cancel out the 12 by dividing 12 from both sides

This is the input/output table for a linear function. Linear functions increase or decrease by a constant value (the slope).

(38 - 19) / (2 -1) = 19

See how every output is +19 the one before it?
then the output following 57 is 57+19 = 76
1 is one 19
2 is two 19's
3 is three 19's
n is 19n

Shania and Pedro are discussing whether it is always possible to solve a right triangle, given enough information, without using
Makovka662 [10]

Answer: Shania is correct.

Step-by-step explanation:

For a right angled triangle, given two sides and an angle, we can use the sine rule or the various trigonometry identities to solve the triangle;

a/sin A = b/sinB

and

sin (angle) = opposite side/hypotenuse

cos (angle) = adjacent side/hypotenuse

tan (angle) = opposite/ adjacent

assuming a is the opposite side of angle A and b is also opposite of angle B

Otherwise, the only way to solve a triangle given two sides only is by the use of the Pythagoras theorem.

Hence, Shania is correct.

The volume of the cylinder is 225(pi) cm³. What is the height of
MA_775_DIABLO [31]

Answer:

it's 25 cm

Step-by-step explanation:

Volume = 225π

or πr²h= 225π

or r²h= 225

or h= 225/r²

here diameter d = 6cm so radius r=d/2 = 3cm

or h= 225/3²

hence h= 25cm
