Hello there,
To find the perimeter you add up all 4 sides of the card. The two measurements are 16 and 25 however, this also the case for the other two sides as the card is a perfect rectangle or square.
So 16+16+25+25= 82
The perimeter is 82 cm
Hope this helps!
The answer is <span>D: The graph of the function is negative on (3,infinity).</span>
Answer:
9x
9 is the coefficient
Step-by-step explanation:
5x + 4x
These are like terms (they both have the same variable (x))
5x + 4x = 9x
The coefficient is 9, since it's the number in front of a variable.
Hope this helped!
The answer is the first one hope this helps!!
Answer:
x=-2, y=2
Step-by-step explanation:
-8x +4y=24
-7x+7y=28
substitute 4y=24+8x
y=6+2x in second equation and hence we find X=-2
put value of X in either equation and get value of y=2
