If f(x) = x2 + 4x - 12, find f(2).
Answer:
-3
Step-by-step explanation:
Please write this as f(x) = x^2 + 4x - 12. "x^2" represents "the square of x."
f(2) is the value of this function when x = 2:
f(2) = f(2) = (2)^2 + 4(2) - 12 = 9 - 12 = -3
Solve for x in the equation: 5x +14 = 2x - 4
Someone help
Answer:
x = -6
Step-by-step explanation:
5x +14 = 2x - 4
Subtract 2x from each side
5x-2x +14 = 2x-2x - 4
3x +14 = -4
Subtract 14 from each side
3x+14-14 = -4-14
3x = -18
Divide each side by 3
3x/3 = -18/3
x = -6
Answer:
x = -6
Step-by-step explanation:
5x+ 14 = 2x - 4
-2x -2x
3x+14= -4
-14 -14
3x = -18
3x/3 = -18/3
x = -6

Question 8
A science club rents a bus for a trip to a state park. The bus rental is
$350, and admission to the park is $8 per person. The cost of the bus
rental will be shared equally. Write an expression that can be used to
determine the cost of the trip for each club member.
Let m be the number of club members.
Since they will share the $350 cost of the bus equally, then each member pays 350/m dollars for their share of the bus cost.
The admission is $8 per person, so the total cost per person is;
[tex]\frac{350}{m} +8[/tex]
This figure is a square, with side lengths as shown. What are the perimeter and the area of the square?
Answer:
Step-by-step explanation:
Parameters:
As square has all equal sides in his shape.
then length and width will be equal.
parameters will be
LENGTH,LENGTH,WIDTH,WIDTH
Area:
area of square is known as A= a^2
a= parameter of square (as all parameters are equal,you put one parameter to find area of square)
The required perimeter of the square is 4 times side and the area of the square is ( side ) ².
Given that,
To determine the perimeter and the area of the square.
A square is defined as it is a four-sided polygon, having angles of 90° on its vertices, and the length of all four sides is equal.
What is the perimeter?Perimeter is the measure of the figure on its circumference or it is overall boundary length of the figures.
Here,
The perimeter of the square is given as the sum of all sides,
= side + side + side + side
= 4 x side
The area of the square is multiplied of two adjacent side
= side x side
= ( side )²
Thus, the required perimeter of the square is 4 times side and the area of the square is (side)².

CAN SOMEONE MAKE SENSE OUT OF THIS. please i need explaining!!! Shawn's square living room needs new flooring. He needs 196 square feet of flooring to cover the living room. What are the dimensions of Shawn's living room? Since Shawn's living room is in the shape of a square, we know that the length of each side is exactly the same. If we let s represent the length of the room, we can write an equation using the area of a square formula (A = s2). A=s•s=s2=196 Using the definition of square root: s2 = 196 s = ±√196 s = ±14 But since we are talking about the dimensions of Shawn's living room, the only real solution to this problem is 14 feet (because a solution of -14 feet would not be possible).
Step-by-step explanation:
Shawn's living room is a square, so all four sides are the same length. Area of a square is A = s², and we know the area is 196 ft². If substitute this for A:
196 ft² = s²
Take square root of both sides:
s = √(196 ft²)
s = ±14 ft
Since measurements of lengths can't be negative, s must be +14 ft. So Shawn's living room is 14 ft x 14 ft.
Answer:
14 ft x 14 ft.

help me find b and c
Answer:
b = 48 °, c = 46°
Step-by-step explanation:
c = 46 ° as between parallel lines, alternate opposite angles are equal.
since opposite angles are equal 94 ° = 46 ° + additional angel
therefore b = 94° - 46 ° = 48 ° , as sum of 2 internal angles of a triangle is equal to opposite exterior angle.

At its highest point, the elevation of a country is 5,762 feet above sea level. At its lowest point, the elevation of the country is 8 feet below sea level. Answer parts a through c
Answer:
Step-by-step explanation:
5,762 - (-8)
The total difference between the highest point and the lowest point of the country is given as 5, 770 feet.
Given that,
At its highest point, the elevation of a country is 5,762 feet above sea level. At its lowest point, the elevation of the country is 8 feet below sea level.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Highest point = 5,762
The lowest point below the sea level = -8 feet
Total difference in the point = 5762 - (-8) = 5770 feet
Thus, the total difference between the highest point and the lowest point of the country is given as 5, 770 feet.

10 – 2(2x + 2) > 14
Help meeee
Answer:
x < -2
Step-by-step explanation:
1. Original Inequality: 10 – 2(2x + 2) > 14
2. 10-4x-4>14
Distribute the -2 to 2x and 2.
3. Simplify the left side: 6-4x>14
Do 10-4
4. Subtract: -4x>8
Subtract 6 from both sides to get x by itself
5. Divide: x< -[tex]\frac{8}{4}[/tex]
You want to divide by -4 that way you can find what x is. When you divide OR multiply by a negative number in an inequality you are going to need to switch the way the sign is facing.
6. Simplify: x< -2
7. Check:
10-2(2(-3) +2) > 14
10-2(-6 + 2)
10-2(-4)
