A = (12 x 8 x 3) + (1/2 x 8 x 6.9) + (1/2 x 8 x 7 x 3)
A = 288 + 27.6 + 84
A = 399.6 m²
Answer:
the sum of two numbers is 27. their difference is 5. find the number
Step-by-step explanation:
Let x be the first number and y be the second number ... so we have
x + y = 27
x - y = 5 Adding the equations, we have
2x = 32 Dividing through by 2, we have
x = 16 And substituting or x in the first equation, we have
16 + y = 27 Subtract 16 from both sides
y = 11
What you do is you distribute the 5.
So your answer would be 5x+15
