Answer:
the answer is 21
Step-by-step explanation:
4x to the power of 2 + 5x
so: 4*1 the power of 2 +5*1
4to power of 2 +5
and 4 to the power of 2 equals 16 (because 4*4=16) and +5
so 16+5=21
Let x represent the width of the garden(s). Then the length of the second garden is (3x+3). The area is the product of length and width,
90 = x(3x+3)
30 = x(x+1)
At this point, you can recognize that 5 and 6 are factors of 30 that will satisfy this equation, or you can solve the quadratic
x² +x -30 = 0
(x +6)(x -5) = 0
x = 5 . . . . . . . the negative solution does not apply
The width of the garden is 5 m.
Answer:
In the allocated budget of $130 , the business person can travel 462.55 miles a day.
Step-by-step explanation:
The daily rate of car service = $37.49
Cost per mile of the car = 20 cents = $ 0.20
Total allocated budget for each day = $130
Now, out of the total budget :
The actual travelling budget = Total Budget - Daily car rate
= $130 - $37.49
= $92.51
So, the actual travelling budget each day = $92.41
Now, 
= 
or, the number of miles traveled = 462.55 miles
Hence, in the allocated budget of $130 , the business person can travel 462.55 miles a day.
4x+5=13
Start by subtracting 5 from both sides:
4x+5-5=13-5
4x=8
Divide both sides by 4 to isolate x
x=2
