Answer:
Step-by-step explanation:
<u>We know that:</u>
- -4 + x = 16 [x = difference between two temperatures]
<u>Solution:</u>
- -4 + x = 16
- => x = 16 + 4
- => x = 20
Hence, the difference between the two temperatures is 20°.
Step-by-step explanation:
Since both terms are perfect squares, factor using the difference of squares formula, a 2 − b 2 = ( a + b ) ( a − b ) where a = 7 and b = a + x . − ( 7 + a + x ) ( a + x − 7 )
Its 4% do i get brainiest???
Let the length and width of the square board be x cm, when 4 cm are cut of from the corner, the dimensions of the box will be:'
length=(x-8) cm
width=(x-8) cm
height=x cm
thus the volume will be:
4(x-8)(x-8)=144
4(x^2-16x+64)=144
this can be written into:
x^2-16x^2+64=36
solving the above gives us:
x=2 or x=14
when x=2, the dimensions will be negative. Thus we take x=14 cm, the original dimensions are 14 cm by 14 cm
8/11 is the fraction
To derive this simply put
72.727272/100 and it reduces to 8/11
