Answer:
see below
Step-by-step explanation:
(-3) ^2
(-3)*(-3)
A negative times a negative
9
If the problem is
- (3) ^2
- (3*3)
- 9
The coefficients in the expression are 3 and 7.
An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
Now the given expression is,
9 - 4 + 3b + 7a
So, from the given expression we can see that there are 4 terms, 2 constants and 2 coefficients.
The coefficient of b is 3,
and coefficient of a is 7.
So, there are 2 coefficients in the given expression.
Thus, the coefficients in the expression are 3 and 7.

Answer:
The coefficients are b and a
The perimeter of a triangle with vertices located at (-1, 4), (2, 7), and (1, 5) is 8.71 units
The coordinates are given as:
(-1, 4), (2, 7), and (1, 5)
Calculate the distance between these points using:
So, we have:
The perimeter P is then calculated using:
P = 4.24 + 2.24 + 2.24
Evaluate the sum
P = 8.71
Hence, the perimeter of the triangle is 8.71 units

b. 48
c. none of these choices is correct
d. 9
e. 16?
We have been given that
2 cups flour + 3 eggs + 1 tbs oil → 4 waffles
In order to make 4 waffles we need 3 eggs.
Thus, to make 1 waffle we need 3/4 eggs.
Now, in 1 dozen there are 12 waffles. Hence, to make 12 waffles we need
Therefore, 9 eggs are needed to make 1 dozen waffles.
D is the correct option.
