Answer:

option is B)

Step-by-step explanation:

2x is a perfect square. but x is not a perfect square, this brings us to the conclusion tht prob x is 2.

2x = 4

hence correct option is B) 4x is a perfect square, as 4x4=16, which is a perfect square...

Here’s a graph of a linear function. Write the equation that describes that function

inessss [21]

Answer:

The equation of the line is y = 1/4x - 4

Step-by-step explanation:

In order to find this, start with two points that are on the line. We'll use (0, -4) and (4, -3). Now we can use the slope formula to find the slope.

m(slope) = (y2 - y1)/(x2 - x1)

m = (-4 - -3)/(0 - 4)

m = -1/-4

m = 1/4

Now that we have this, we can use that slope and a point in point-slope form. Then we solve for y to get the equation.

y - y1 = m(x - x1)

y - -4 = 1/4(x - 0)

y + 4 = 1/4x

y = 1/4x - 4

(p-4)^2=4p complete the square if possible

Assoli18 [71]

Answer:

$p=6+2 \sqrt{5}, p=6-2 \sqrt{5}$

Step-by-step explanation:

Step 1: Given expression is $(p-4)^{2}=4 p$ .

Step 2: To write the equation in the quadratic form, subtract 4p from both sides of the equation.

$\Rightarrow(p-4)^{2}-4 p=4 p-4 p$

$\Rightarrow p^{2}-8 p+16-4 p=0$

$\Rightarrow p^{2}-12 p+16=0$

$\Rightarrow p^{2}-12 p=-16$

Step 3 :Add $\left(\frac{-12}{2}\right)^{2}$ on both sides of the equation.

$\Rightarrow p^{2}-12 p+\left(\frac{-12}{2}\right)^{2}=-16+\left(\frac{-12}{2}\right)^{2}$

$\Rightarrow p^{2}-12 p+36=-16+36$

$\Rightarrow(p-6)^{2}=20$

Step 4: Taking square root on both sides of the equation.

$(p-6)=\pm \sqrt{20}$

$p=6 \pm 2 \sqrt{5}$

Hence, $p=6+2 \sqrt{5}, p=6-2 \sqrt{5}$ .

1kg costs £1.28. what is the cost of 250g

vivado [14]

First, convert 1 kg to g.

1 kg = 1000 g

So 1000 g = 1.28

Set up a proportion:

1000/1.28 = 250/x

Cross multiply:

1000x = 320

Divide 1000 to both sides:

x = 0.32

So 250g costs £0.32
