Remember that a coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression in Math. The coefficient of "x" would be -5.

Another coefficient is 4, but there is only -4, which isn't in the equation.

There are two triangles. Triangle 1 has 3 legs labled a, b, and c. Leg a is 4x + 2, leg b is 5x - 4, and leg c is 7x + 7. Triangle 2 has 3 legs labeled a', b', and c'. Leg a' is x + 3, leg b' is x + 7, and leg c is 2x - 5. You must do 2 things. The first thing is to write an expression in simplest form for the perimiter of each triangle. The second thing you must do is write another expression in simplest form that shows the difference between the perimiter of Triangle 1 and the perimiter of Triangle 2.

(5x^2 + x - 3) - (-2x^3 + 4)
= 5x^2 + x - 3 + 2x^3 - 4 (distributing the negative sign)
= 2x^3 + 5x^2 + x - 7

If you earned 6t + 2 dollars on Monday and 9t - 6 dollars on Tuesday, then your total earnings would be (6t + 2) + (9t - 6) dollars.
Combining like terms, we get 15t - 4 dollars.
Therefore, your total earnings were 15t - 4 dollars.
Combining like terms, we get 15t - 4 dollars.

When multiplying variables with exponents, we add the exponents.
So, f^2 x f^4 can be simplified as:
f^2 x f^4 = f^(2+4) = f^6
Therefore, f^2 x f^4 is equal to f^6.
So, f^2 x f^4 can be simplified as:
f^2 x f^4 = f^(2+4) = f^6

When dividing exponential expressions with the same base, we subtract the exponents.
So,
64^10 / 64^5 = 64^(10-5) = 64^5
Therefore, 64^10 / 64^5 is equal to 1,073,741,824 (64 raised to the 5th power).
So,
64^10 / 64^5 = 64^(10-5) = 64^5
Therefore, 64^10 / 64^5 is equal to 1,073,741,824 (64 raised to the 5th power).

When dividing exponential expressions with the same base, we subtract the exponents.
So,
3^3/3^6 = 3^(3-6) = 3^(-3)
Recall that a negative exponent indicates the reciprocal, so
3^(-3) = 1/3^3 = 1/27
Therefore, 3^3/3^6 is equal to 1/27.
So,
3^3/3^6 = 3^(3-6) = 3^(-3)

When multiplying a number by a set of parentheses, we use the distributive property to simplify.
So,
-6(4x + 9) = (-6 x 4x) + (-6 x 9) = -24x - 54
Therefore, -6(4x + 9) simplifies to -24x - 54.
So,
-6(4x + 9) = (-6 x 4x) + (-6 x 9) = -24x - 54
Therefore, -6(4x + 9) simplifies to -24x - 54.

Perimeter of Triangle 1 = a + b + c = (4x + 2) + (5x - 4) + (7x + 7) = 16x + 5
Perimeter of Triangle 2 = a' + b' + c' = (x + 3) + (x + 7) + (2x - 5) = 4x + 5
Difference in perimeter between Triangle 1 and Triangle 2 = Perimeter of Triangle 1 - Perimeter of Triangle 2
= (16x + 5) - (4x + 5)
= 12x
Therefore, the expression for the difference in perimeter between Triangle 1 and Triangle 2 is: 12x.
Perimeter of Triangle 2 = a' + b' + c' = (x + 3) + (x + 7) + (2x - 5) = 4x + 5
