A. Divide both sides by 4
You want to get the value of x not 4x so in order to do that u can have divide both sides by 4 to get x alone on one side.
Answer
given,

to find the critical point of the given expression
fist differentiating the function



now equating differential equation to zero


now,
-x + 3 = 0 and eˣ ≠ 0
x = 3
the critical number will be equal to x = 3


Answer:
A=50.3
Step-by-step explanation:
A= πr²
A= π x 4²
A= 3.142 x 16
A=50.272
A≈50.3
Answer:
1500÷30=50
40× 50=2000
2000-1500=500.
therefore the answer is500
Answer:
L = 10 in
W = 2.5 in
Step-by-step explanation:
Let length be L and width be W
Perimeter = L + L + W + W
Perimeter =2L + 2W
given than length is 4 times the width, or
L = 4W (substitute this back into the perimeter equation above)
Perimeter =2L + 2W
Perimeter =2(4W) + 2W
Perimeter =8W + 2W
Perimeter = 10W
given that the perimeter is 25in
25 = 10W
W = 25 / 10 = 2.5 in (answer for width)
L = 4W = 4(2.5) = 10 in (answer for length)
