A=1/2b(c+d) solve for c

TiliK225 [7]

Answer:

c = $\frac{2A}{b}$ - d

Step-by-step explanation:

Multiply both sides by 2 to eliminate the fraction

2A = b(c + d) ← divide both sides by b

$\frac{2A}{b}$ = c + d ← subtract d from both sides

$\frac{2A}{b}$ - d = c

1. Which monomial has the same degree as 6a2b8c? A 18t8 B 12p6q5 C 9a5b3c2 D 6w4x2y3z3

Olegator [25]

Answer: "B. $12p^6q^5$

Step-by-step explanation:

The given monomial : $6a^2b^8c$

Degree of this monomial = Sum of powers of variables=2+8+1= 11

Let's check all the options

A $18t^8$

Degree = 8

B $12p^6q^5$

Degree = 6+5 =11

C $9a^5b^3c^2$

Degree = 5+3+2=10

D $6w^4x^2y^3z^3$

Degree =4+2+3+3=12

We can see that only option B has degree 11.

So, the monomial has the same degree as $6a^2b^8c$ is "B. $12p^6q^5$ "
