Answer:
Step-by-step explanation:
1) 1 km = 1000 m
7.8 km = 7.8 * 1000
= 7800 m
2) 1 g = 1000 mg
1.6 g = 1.6 * 1000
= 1600 mg

Answer:
10x^2+8x+3
Step-by-step explanation:
<h3><u>Answer:</u></h3>
- <u>x </u><u>-</u><u> </u><u>8</u>
<h3><u>Solution</u><u>:</u></h3>
We are given a rectangle with one of its sides ( length ) equal to ( x - 7 ) Meters.
- Also we are given the area of the rectangle as x² - 15x + 56 square meters .
We have to find the expression for another side of the rectangle i.e it's width
We will use the formula of area of rectangle to find the expression :
- <u>A</u><u>rea </u><u>=</u><u> </u><u>length </u><u>×</u><u> </u><u>width</u>
Therefore,
ㅤㅤ➝ A = l × w
ㅤㅤ➝ x² - 15x + 56 = ( x - 7 ) × w
ㅤㅤ➝ x² - 8x -7x + 56 = ( x - 7 ) × w
ㅤㅤ➝ (x² - 8x )( - 7x + 56 ) = ( x-7 ) w
ㅤㅤ➝ x( x - 8 )-7( x - 8 ) = ( x - 7 )w
ㅤㅤ➝ ( x - 8 )( x - 7 ) = ( x - 7 )
ㅤㅤ➝ ( x - 8 )w = ( x - 8 )( x - 7 )
ㅤㅤ➝ w = ( x - 8 )( x - 7 ) / ( x - 7 )
ㅤㅤ➝ <u>w = ( x - 8 )</u>
