O-6
Answer:
-6
Step-by-step explanation:
f(x) = x^2 + 5x
Let x = -2
f(-2) = (-2)^2 + 5(-2)
= 4 -10
= -6
witch is greater -6 or 7
Answer:
7
Step-by-step explanation:
Very easy problem once you understand "negative numbers."
"-6" is a negative number. A negative number is a number below zero. You'll know if a number is negative because it has a minus symbol (this symbol - ) before it. -6 is a negative number and below zero. 7 is a number above zero so therefore 7 is a greater number.
Here's another thing about negative numbers. Even though the number may look "bigger" (for example -7) is actually a SMALLER number than -6. The more "negative a number is" the smaller it is. Hope this helps and have a nice day!

6*4+2 / 2-7
1: 20+2 / 2-7
2: 20+1-7
3: 21-7
14
In this equation we need to use OoO ( order of operations) Or Pemdas!
The first step seince there arnt any exponents or parenthesies we need to multiply 6*4=20 Next we need to divide 2 by 2 wich is 1. Now that we got multiplication and divition done we add 10+1 wich is 21. Last but not least wesubtract 21 by 7= 14 Therefor the awnser is 14!
Sandy didnt follow Pemdas and she did not go from left to right. She added and did not divide on step one and on step 2. All the other steps are right sandy messed up on step 1. Therfore sandy got a difrent awnser than she was soupossed to.

Caroline drives 37.5 miles in 30 minutes. If she drove three hours in total at the same rate, how far did she go?
Hey there! I'm happy to help!
3 hours is 180 minutes as there are 60 minutes in 1 hour. How many times does 30 minutes go into 180 minutes?
180/30=6
So, we have six of these 30 minute time slots that fit into 3 hours. So, we multiply our 37.5 miles by six to find the total mileage!
37.5×6=225
Caroline drove 225 miles.

Step-by-step explanation:
Type the correct answer in the box. Use numerals instead of words. The height of a baseball, in feet, is represented by this expression, where t is time in seconds.
Answer:
31 feet.
Step-by-step explanation:
It is mentioned in the question that
Height of baseball expressed in feet
T = time in seconds
Also
[tex]h= -16t^2+64t+3[/tex]
Now the time is 3.5 so put this value to the above equation
h = -16(3.5)^2 + 64(3.5) + 3
= -16(2.25) + 224 + 3
= -196 + 227
= 31
Therefore the height of a baseball is 31 feet and the same is to be considered
Nico and Karina wrote these statements in their math journals. Nico's Statement Karina's Statement A 4-sided polygon with at least one pair of parallel sides must be a parallelogram. A 4-sided polygon with at least one pair of parallel sides must be a trapezoid. Which describes the accuracy of their statements and why?
Answer:
the person above me is correct, its d
Step-by-step explanation:
Karina's statement is accurate, as the minimum requirement for a trapezoid is one pair of parallel sides.
What is a Trapezoid?A trapezoid is a polygon with four sides. If one side of a quadrilateral is parallel to the other it is a Trapezoid.
The statement written by Nico is
A 4-sided polygon with at least one pair of parallel sides must be a parallelogram.
The statement written by Karina is
A 4-sided polygon with at least one pair of parallel sides must be a trapezoid.
Nico's statement is incorrect because a polygon with a minimum of 2 pairs of parallel sides is a Parallelogram.
Karina's statement is correct, as a minimum of one pair of parallel sides is needed to make a trapezoid, more than one pair is a parallelogram but that is also a trapezoid with two pairs of parallel sides.
Therefore, Karina's statement is accurate.

A moving truck has a length that measures 10 ft, a width of 6 ft,
and a height of 61, Ft. What is the volume of the
moving truck?
Answer:
3660 ft^3
Step-by-step explanation:
Answer:
the volume of the truck = 390 ft³
Step-by-step explanation:
given:
Length that measures 10 ft, a width of 6 ft,
and a height of 6 1/2, Ft.
find:
What is the volume of the
moving truck?
volume of a rectangular prism = L x W x H
where L = length = 10 ft.
W = width = 6 ft.
H = height = 6 1/2 ft
plugin values into the formula:
V = 10 x 6 x 6.5
V = 390 ft³
therefore,
the volume of the truck = 390 ft³
