45÷9=5 So then 6x5=30 A=30
Answer:
The length is 7 meters
Step-by-step explanation:
Formula: P = 2L + 2W
Plug in 24 for the perimeter and 5 for the width
New equation: 24 = 2L + 2(5)
Simplify: 24 = 2L + 10
Subtract 10 from both sides: 24 - 10 = 2L + 10 - 10
Simplify: 14 = 2L
Divide both sides by 2: L = 7
<u>Answer: L = 7</u>

Answer:
Acute Triangle
Step-by-step explanation:
<u><em>Angles in a triangle add up to 180 degrees.</em></u>
So,
x+2x+2x = 180
=> 5x = 180
Dividing both sides by 5
=> x = 36
<u><em>So, The lengths are:</em></u>
=> 36
=> 72
=> 72
<em><u>Since all the angles are less than 90 degrees, It is an acute triangle.</u></em>
Answer:
Each goal gives 5 points and a penalty costs 7 points.
Step-by-step explanation:
Let a penalty cost = x points
And a goal gives = y points
Ben makes 7 goals and 2 penalties ending the game with 21 points,
7y - 2x = 21 --------(1)
Alyssa makes 10 goals and 8 penalties ending the game with (-6) points,
10y - 8x = -6
5y - 4x = -3 --------(2)
Equation (1) multiplied by 2, then subtracted from equation (2),
(5y - 4x) - 2(7y - 2x) = -3 - 2(21)
5y - 4x - 14y + 4x = -3 - 42
-9y = -45
y = 5
From equation (1)
7(5) - 2x = 21
35 - 2x = 21
2x = 35 - 21
2x = 14
x = 7
Therefore, each goal gives 5 points and a penalty costs 7 points.
