For this question it is the difference of two perfect squares. This means your final answer will be (2x - 5)(2x + 5). This answer is not listed so it would be none of the above.

After review, B technically works because it is the difference of two perfect squares. This allows you to take the square root of each term while ignoring the sign and then place that back in with the original sign.

-10 x + 4 = 52 x=___ help
Strike441 [17]

Answer: x=-4.8

Step-by-step explanation:

Given

-10x+4=52

Subtract 4 on both sides

-10x+4-4=52-4

-10x=48

Divide -10 on both sides

-10x/-10=48/-10

x=-4.8

Hope this helps!! :)

Can someone please help me with my maths
Korvikt [17]

Answer:

a

Step-by-step explanation:

Recall that the "point-slope" form of a linear equation may be expressed as

y = mx + b,

where  m is the gradient.

If m is negative, the gradient is negative.

If m is positive, the gradient is positive.

In our case, if we consider option A,

x + 3y = -2  (rearranging)

3y = -x -2

y = (-1/3) x - (2/3)

if we compare this to the general equation at the top, we can see that

gradient, = m = (-1/3) which is negative.

hence option a has a negative gradient.
