LenKa [72]

Answer:

$If\ old\ scale\ is\ taken:\ Length=45\ ft,\ Width=42\ ft\\\\If\ new\ scale\ is\ taken:\ Length=36\ ft,\ Width=33.6\ ft$

Step-by-step explanation:

Older Scale:

$2\ in=3\ ft\\\\\Rightarrow 1\ in=\frac{3}{2}\ ft\\\\Length=30\ in\\\\Length=30\times \frac{3}{2}\ ft\\\\Length=45\ ft\\\\Width=28\ in\\\\width=28\times \frac{3}{2}\ ft\\\\width=42\ ft$

New scale:

$4\ in=5\ ft\\\\\Rightarrow 1\ in=\frac{5}{4}\ ft\\\\Length=30\ in\\\\Length=30\times \frac{5}{4}\ ft\\\\Length=36\ ft\\\\Width=28\ in\\\\width=28\times \frac{5}{4}\ ft\\\\width=33.6\ ft$

Line l bisects PQ at point M. Find value of X

Vanyuwa [196]

Answer:

x = $\frac{18}{7}$

Step-by-step explanation:

Since l bisects PQ at M then M is the midpoint of PQ, hence

PM = MQ, that is

5x - 7 = 11 - 2x ( add 2x to both sides )

7x - 7 = 11 ( add 7 to both sides )

7x = 18 ( divide both sides by 7 )

x = $\frac{18}{7}$

3241004551 [841]

See each answer below.

1) If we subtract 7 from both sides and try to take the square root, we are taking the square root of -7. Therefore, there are no solutions.

2) Dividing by 3 and taking the square root gives an answer of 0.

3) Add 4, multiply by 4 and finally take the square root of each side.You will get positive or negative four.

4) Divide by 4 and then take the square root. You have positive or negative 5/2.
