Hi!
So this is an algebra question. We basically want to know what number minus 2 and 1/2 is going to equal 7 and 1/2. An easy way to check for that first number is adding those two numbers together
So we take 2 and 1/2 + 7 and 1/2 , and because they have the same denominator we can add the two numbers . 2 + 7 = 9 and then 1/2 + 1/2 = 1 so 9+ 1 = 10
10- 2 1/2 = 7 1/2
Answer:
156
Step-by-step explanation:
While solving we will have to use the area formula of the rectangle, which is :A=w*l ; length*width=A.
Steps:
1)let’s consider that the shape is a full rectangle. => 16*12=192.
2)9*2=18 -> 18*2=36
3)192-36=156.
Answer:
steps below
Step-by-step explanation:
f(x) = 4√x - 2x ... x≥0
f'(x) = 2/√x - 2
critical points: x=0, x=1
x=1 y = 4√1 -2x1 = 2
extreme: (<u>1</u>,2) tangent line parallel to x axis: y = 2 .... <u>x = 1</u>
x = 0 (x≥0): (0,0) tangent line parallel to y axis: <u>x = 0</u>
