Sub g to (-3) and then solve from there using PMDAS and equation solving skills, Photomath is a fantastic resource
Hello!
We use different formulas to calculate the areas of different shape.
RECTANGLE:
To find the area of a rectangle, we must simply multiply its length by its width. The formula for its area is:
A = l × w
SEMICIRCLE:
Since the formula for a circle is pi × r × r, we must use the same formula but divide it in half, because a semicircle is a half circle, which is why its area would also be half of a circle's. The formula for a semicircle's area is:
A = 1/2 pi × r × r
Tip:
Write these formulas down and memorize them so that you don't forget them. You'll have to use these formulas quite often when finding the area of these shapes.
Answer:
The two numbers are 58 and 60
Step-by-step explanation:
let the two numbers be x and y
then:
y+3x=234
since the two numbers are consecutive even integers then y=x+2
and since y+3x=234
then (x+2)+3x=234
then 4x+2=234
then 4x=234–2
then x=232/4=58
then the other number (y) = x+2= 58+2=60
Answer:
1.4 and 2.3 (repeating)
Step-by-step explanation:
(2 × 2 + 5x - 3)
( 4 + 5x - 3)
--3 --3
7 + 5x
-- --
5 5
1.4 = X
(3x + 7)
-- ---
3 3
x = 2.3 (repeating)
First your use kfc and multiply 5/8x4/3 to get ... 20/24= 5/6
