Answer:
Step-by-step explanation:
5+19×2
Multiplication come first before addition
= 5 + 18
= 23
2/3 (3x + 9) = -2(2x + 6)
Step by step
2/3 * 3x and 2/3 * 9 = 2x and 6
which is 2x + 6 (since 6 is a positive put a plus 6 [ + 6 ] )
-2 * 2x and -2 * 6 = -4x and -12
which is -4x - 12 (since 12 is negative put a minus 12 [ - 12 ])
We now have 2x + 6 = -4x - 12
now add 4x on both sides
2x + 6 + 4x = −4x − 12 + 4x
6x + 6 = −12
now Subtract 6 from both sides.
6x + 6 − 6 = −12−6
6x=−18
finally Divide both sides by 6.
6x/6 = -18/6
x = -3
The answer is x=−3
Answer:
trapizoids
Step-by-step explanation:
How much left is the simply the area.
Area = length * width
Area = 7 feet * 2 2/9
Area = 7 * 20/9 = 140/9
Area = 140/9 square feet.
