Answer:

7x² - 3x - 4

Step-by-step explanation:

Step 1: Write expression

(6x² - x + 3) + (-2x + x² - 7)

Step 2: Combine like terms (x²)

7x² - x + 3 - 2x - 7

Step 3: Combine like terms (x)

7x² - 3x + 3 - 7

Step 4: Combine like terms (constants)

7x² - 3x - 4

If x+3/3=y+2/3, then x/3= A) y/3 B)y-1 C)y/2 D)y+1

Vlada [557]

Answer:

y/2

Step-by-step explanation:

x+3=y+2

------ --------

3 2

Using cross products

2(x+3) = 3(y+2)

Distribute

2x+6 = 3y+6

Subtract 6 from each side

2x+6-6 = 3y+6-6

2x= 3y

Divide each side by 2

2x/2 = 3y/2

x = 3/2 y

We want to find x/3

Divide each side by 3

x/3 = 3/2 y * 1/3

x/3 = 1/2 y

Is Rey's claim correct?Justify your answer.

gavmur [86]

TRIANGLE A: (5 x 6)÷2= 15ft.

TRIANGLE B: (4 x 8)÷2= 16ft.

16+15= 31ft.

TRIANGLE C: (9 x 14)÷2= 63ft.

Therefore, Rey's claim is incorrect
