Which expression is equal to 7 + 6X5-2?
A) 13X5-2
B) 7+11-2
C) 13 X 3
D) 37-2
Answer:
So, in the expression 7 + 6X5-2, we must first multiply 6 and 5, which gives 30. Then we must add 7 and 30, which gives 37. Finally, we must subtract 2 from 37, which gives a final score of 35.
Therefore, the expression 7 + 6X5-2 is equal to 37-2. The correct answer is D) 37-2.

The cost per ounce is $0.156
What is ounce?An ounce is a unit of weight and mass in the Imperial and United States customary systems of measurement. It is commonly used to measure the weight of precious metals such as gold, silver, and platinum. In the US, the ounce is equal to 28.35 grams. The ounce is also used to measure the weight of food items, liquids, and other substances. In the UK, the ounce is equal to 28.4 grams. The ounce is also used to measure the weight of postage stamps, coins, and other small items. The ounce can also be used to measure the volume of a liquid. One fluid ounce is equal to 29.57 milliliters. A dry ounce is equal to 28.35 grams. An ounce is also one-sixteenth of a pound.
Solution:
1 pound is equal to 16 ounce
6 pounds of coffee = 6 x 16 = 96 ounce

The correct option is (a)
As x ⇒ ∞, f(x) ⇒ -∞ and As x ⇒ -∞, f(x) ⇒ ∞.
What is Polynomial function ?
The terms poly and nomial combine to form the word polynomial. We can define polynomials as "algebraic expressions with many terms" because "poly" means many and "nomial" denotes the term.
Given : f(x)= -2x^3 +3x^2 +2x -1
In order to determine the end behavior of the polynomial function, we are required to check the highest degree of the polynomial and the coefficient of the term which has highest degree.
Here, The highest degree of the polynomial is 3 and the coefficient of the term which has highest degree is -2.
Since, the coefficient is negative, the graph will move right down which means as x ⇒ ∞, f(x) ⇒ -∞.
Similarly, the degree is odd which states that the sign will be opposite of what the coefficient has. So, As x ⇒ -∞, f(x) ⇒ ∞.
Hence, As x ⇒ ∞, f(x) ⇒ -∞ and As x ⇒ -∞, f(x) ⇒ ∞.

A polygon's interior
angles add up to 4320°.
How many sides does the
polygon have?
Answer:
24 sides
Step-by-step explanation:
The interior angles of a polygon add up to 180(n-2) degrees, where n is the number of sides the polygon has. This means that to find the number of sides a polygon has, we can set up the following equation:
180(n-2) = 4320
Solving for n, we get:
n = (4320 + 360) / 180 = 24
Therefore, the polygon has 24 sides.

What is the equation of a line?The equation of a line is an equation that describes the line. It is given by y = mx + c where
m = gradient and c = y - interceptHow to find the equation that describes the line?Since the equation of a line is given by y = mx + c and we have the points from the table (-5, 2) and (0, 7)
Substituting these evalues into the equation, we have
y = mx + c
2 = m(-5) + c
2 = -5m + c (1)
Also, the point (0,7),we have
y = mx + c
7 = m(0) + c
7 = 0 + c
c = 7
Substituting c = 7 into equation (1), we have that
2 = -5m + c
2 = -5m + 7
2 - 7 = -5m
-5 = -5m
m = -5/-5
m = 1
Substituting m = 1 and c = 7 into the equation for the line, we have
