Answer: Option 'B' is correct.

Step-by-step explanation:

Since we have given that

there are two factors i.e.

4x-7\ and\ x+4

So, we need to get a polynomial who has these factors :

For this we will use " (x+a)(x+b)=x^2+(a+b)x+ab " .

So, we get ,

(4x-7)(x+4)\\\\=4x^2+16x-7x-28\\\\=4x^2+9x-28

Hence, option 'B' is correct.

The speed of light is about 300,000 kilometers per second. The Sun is about 93 million miles from Earth. How many minutes does i
spin [16.1K]

Answer: 8.3 minutes

Step-by-step explanation:

1 mile is to 1.60934km so 93 million miles is:

= 93 * 1.609

= ‭149,637,000‬ km

Travelling at 300,000 km per second, the number of seconds it takes is:

= ‭149,637,000‬/300,000

= ‭498.79‬ secs

In minutes this is:

= ‭498.79‬/60

= 8.3 minutes

Which symbol creates a true sentence when x equals 3?
Marta_Voda [28]
Hi <span>Tysona90!
Let's write it with the X as a 3
8*3-4*3_7(10-3) Now let's solve it 8*3 is 24 and 4*3 is 12 so then we do 24-12 which is 12. So now we have 12_7(10-3) so let's solve the other half which is 10-3 is 7 times 7 (since parenthesis can also mean multiplication) which is 49 so we now have 12_49 which means the answer is A.
Hope this helps!</span>

solniwko [45]

Answer:

$33.85

Step-by-step explanation:

Let X be the initial bill:

(100 + 20.7)% of X was paid

120.7/100 × X = 40.86

X = 40.86 × 100/120.7

X = 33.85252693
