Perimeter = 2L + 2W

Area = L x W

Rectangle A:

Perimeter = 2(6) + 2(8) = 12 + 16 = 28 cm

Area = 6 * 8 = 48 cm^2

Rectangle B:

Perimeter = 2(4) + 2(12) = 8 + 24 = 32 cm

Area = 4 x 12 = 48 cm^2

A worker makes $ 600,000 a month, how much do you earn in a year?
Minchanka [31]
If a worker makes 600,000 a month, we can multiply that to 12, since there are 12 months in a year. 600,000 x 12 = 72,000,00, so the worker makes $72,000,00 a year. :)

statuscvo [17]

Answer:

r = 14

Step-by-step explanation:

9r - 66 = 116 - 4r

+4r                 +4r

13r - 66 = 116

     +66    +66

13r = 182

divide both sides by 13

r = 14

Two functions are given below: f(x) and h(x). State the axis of symmetry for each function and explain how to find it.
andrew-mc [135]

Answer:

f(x):

x =  - 4

g(x)

x = 1

Step-by-step explanation:

When a function is of the form:

f(x) = a {(x - h)}^{2}  + k

The equation of the axis of symmetry is

x = h

The given function is

f(x) = 3 {(x + 4)}^{2}  + 1

We can see that h=-4

Hence the equation of axis of symmetry is

x =  - 4

From the graph, the axis of symmetry of h(x) is the vertical line that divides the parabola into two congruent halves.

This line is

x = 1

The sides of a triangle are consecutive integers.if its perimeter is 126cm,find the lenghts of the sides.
Neko [114]
X + (x + 1) + (x + 2) = 126
3x = 123
x = 41
So the sides are 41, 42 and 43

Use the Pythagorean theorem to find the unknown side of the right<br>triangle​
kramer

Answer:

26

Step-by-step explanation:

→ Utilise Pythagoras theorem

a² + b² = c²

→ Substitute in the values

10² + 24² = c²

→ Simplify

100 + 576 = c²

→ Simplify further

676 = c²

→ Square root both sides to isolate c

26 = c
