Answer:

10

Step-by-step explanation:

If ABCD is a rectangle, then AB=CD and AC=BD.

  • AC=BD, so x+6=2x-4
  • Subtract, -x+6=-4
  • Subtract, -x=-10
  • Make positive, x=10

Check work:

  • 10+6=2(10)-4
  • 10+6=20-4
  • 16=16

2x-7y=12 for y answer please​
Marat540 [252]

Answer: If you want mx + b= y form and you want the y intercept, then the answer would be 2x/7 - 12/7 = y. The y intercept is b, so it is 12/7.

Step-by-step explanation: 2x - 7y = 12

Move -7y to the other side: 2x= 12 + 7y

Subtract 12 to the left side: 2x - 12 = 7y

Then divide 7 into everything: 2x/7 - 12/7 = 7y/7

The 7s in the right side cancel out, so the equation is now: 2x/7 - 12/7 = y

The y intercept is b, which is the second term in the equation, so the

Y Equals : 12/7

Mumz [18]
The correct answer is 64 square units.

The area of the complete shape would be 100 square inches.
10 x 10 = 100

However, we have to remove the 4 corners. Each of the corners is 9 square inches. 3 x 3 = 9

100 - 4(9) = 64

oksian1 [2.3K]
I think it would be 117

Because H is 63
So 90+90+63=243
360-243=117
I used 360 because angles in quadrilaterals add up to 360 degrees
