Answer:
20
Step-by-step explanation:
Given :
Length = l
Width = w
Area of square = 45
Let side of square = x
Area of square = x²
45 = x²
√45 = x
l of rectangle = x + 5 = √45 + 5
w of rectangle = x -5 = √45 -5
Area of rectangle= l * w
Area = (√45 + 5) * (√45 - 5)
Area = 45 - 5√45 + 5√45 -25
Area = 45 -25
Area of rectangle = 20
Only true statement for function f(x) =
is <u>c. if the value of x increases by 1, the value of y will triple</u>.
<u>Step-by-step explanation:</u>
<u>a. the function decreases
</u>
f(x) =
, For value of x<1 function decreases and for x>1 function increases . False statement .
<u>c. if the value of x increases by 1, the value of y will triple.
</u>
For value of x increases by 1 we have ,
. True statement.
<u>b. the function has a y-intercept of (0, 3)
</u>
At y intercept x=0, f(x) =
,
. Function has a y-intercept of (0,3). False statement.
<u>d. the function contains the point (1, 4)</u>
At x=1,
. Function contains (1,12) not (1,4) . False statement.
Answer: Yes.
Step-by-step explanation: if y=12, then 24-12=24 aka 24-y=12
