The answer would be 240 since you are only looking for surface area, which means you wouldn’t include the width
Answer:
( -4, -3 )
Step-by-step explanation:
Let's solve by elimination. Reason being there are no variables without coefficients.
−5y+3x=3 Multiply equation by 3. Each term.
−8y+9x=−12
-15y + 9x = 9 Subtract the to equations
-8y + 9x = -12
___________
-7y = 21
y = -3
Substitute y into original equation
-5(-3) + 3x = 3
15 + 3x = 3 Subtract 15 both sides
3x = -12 Divide by 3, both sides
x = -4
Answer:
width = let width be w
area = 140
length = 2w-6
Area of a rectangle = l*b
⇒ 2w-6*w=140
⇒ 
Answer:
-4182
Step-by-step explanation:
(24-3)-44-4131-28 subtract the numbers in ( ) first
21-44-4131-28 calculate the difference ( subtract in order now)
0 because you can divide them ie 0 is divisible with 5 and 10
