The correct answer is d) 4x2 - 4x + 1.

The area of a square is found by squaring the side length:

(2x-1)? = (2x-1)(2x-1) = 2x*2x - 2x*1 - 2x*1 - = 1(-1) = 4 x 2 - 2x - 2x + 1 = 4x2-4x+1

How do you work out 8x+3=8×+27
Alekssandra [29.7K]

Answer:

No solution

Step-by-step explanation:

8x + 8 = 8x + 27

You then cancel out the 8s. 8 - 8 = 0

Which leaves you with 8 = 27...

Since this is an untrue statement, the answer would be no solution, unless you typed it wrong.

Tell whether the lines for each pair of equations are parallel, perpendicular, or neither
Andru [333]
6y = -x - 7 
<span>y= 6x - 3 </span>
<span>__________________ </span>

<span>y = x/6 + 7/6 </span>
<span>y= 6x - 3 </span>

<span>Compare the gradients, one is 1/6, one is 6. These are not parallel because they aren't the same, and not perpendicular because they aren't negative reciprocals. Therefore, neither.</span>

Nadya [2.5K]

Answer:

<u>100 degrees</u>

Step-by-step explanation:

y = ½ (b + x)

80 = 1/2(60 + x)

80 = 30 + x/2

50 = x/2

x/2 = 50

x = 100

<u>This means that the value of x in this picture is 100 degrees</u>
