(X-8) (x-5)
Using the foil method, you will get x^2-13x+40 when you multiply the terms.

What’s the correct answer for this question?

Ad libitum [116K]

Answer:

Step-by-step explanation:

Both angles add up to 180°

<BCG + <BFG = 180°

2x+146+4x+238=180

6x+384 = 180°

6x = 180-384

6x = -204

Dividing both sides by 6

x = -34

If there aren’t any degrees and it doesn’t state that the triangle is equilateral then you cannot solve this equation without more information

A spring has natural length 24 cm. Compare the work W1 done in stretching the spring from 24 cm to 34 cm with the work W2 done i

Scilla [17]

Answer:

From the analysis W1=W2.

they are directly related

Step-by-step explanation:

the work-done in stretching a spring can be expressed as

$W=\frac{1}{2}kx^2$

where k= spring constant

x= change on length of spring

Hence for W1

Given data

x= 34-24= 10 cm

solving in terms of k we have

$W=\frac{1}{2}k*10^2\\\W=\frac{1}{2}k*100\\\W=50k$

Hence for W2

Given data

x= 44-34= 10 cm

solving in terms of k we have

$W=\frac{1}{2}k*10^2\\\ W=\frac{1}{2}k*100\\\ W=50k$

(Pls help) I need help finding x!

Ray Of Light [21]

Answer:

x ≈ 46°

Step-by-step explanation:

Since the triangle is right use the sine ratio to solve for x

sinx = $\frac{opposite}{hypotenuse}$ = $\frac{10}{14}$ , hence

x = $sin^{-1}$ ( $\frac{10}{14}$ ) ≈ 46°

Mekhanik [1.2K]

Answer:

None

Step-by-step explanation:

Because mode is a set of data values is the value that appears most often. If there is no data value or data values that occur most frequently, we say that the set of data values has no mode.
