Make b the subject of this equation A = 1/2 x b x h

aalyn [17]

The equation is $b=\frac{2A}{h}$

Step-by-step explanation:

Let us revise how to make a variable subject of an equation

Write the equation and circle the variable you want to make it subject
Keep it in one side and move all other in the other side
Make the coefficient of the subject 1

∵ A = $\frac{1}{2}$ × b × h

∵ b is the subject

∴ Multiply the two sides by 2

∴ 2A = b × h

- Divide both sides by h

∴ $\frac{2A}{h}= b$

- Switch the two sides

∴ $b=\frac{2A}{h}$

The equation is $b=\frac{2A}{h}$

Using what you have learned about solving systems of equations, find the number that represents the apple, banana, and cherry.

sineoko [7]

Answer:

$Apple \to 4$

$Banana \to 4$

$Cherry \to 5$

Step-by-step explanation:

Given

$A \to Apple$

$B \to Banana$

$C \to Cherry$

From the rows, the equation is:

$B + 2A =12$ --- (1)

$2B + C = 13$ --- (2)

$A + 2C = 14$ --- (3)

Make A the subject in: $A + 2C = 14$

$A = 14 -2C$

Substitute $A = 14 -2C$ in $B + 2A =12$

$B + 2(14 - 2C ) = 12$

$B + 28 - 4C = 12$

Make B the subject

$B = 4C - 28 +12$

$B = 4C -16$

Substitute $B = 4C -16$ in $2B + C = 13$

$2(4C - 16) + C = 13$

$8C - 32 + C = 13$

Collect like terms

$8C + C = 13+32$

$9C = 45$

Divide by 9

$C = 5$

Recall that:

$B = 4C -16$

$B =4*5-16$

$B =20-16$

$B =4$

Recall that:

$A = 14 -2C$

$A= 14 -2*5$

$A= 14 -10$

$A =4$

Hence:

$Apple \to 4$

$Banana \to 4$

$Cherry \to 5$

loris [4]

Answer:

(x+6)(x-6)

Step-by-step explanation:

Given: x²-36

Difference of Squares Formula: x²-a²=(x+a)(x-a)

Since 6²=36: x²-6²=(x+6)(x-6)
