A cooling liquid's temperature \( G \) (in degrees Celsius) after \( y \) minutes follows the equation: \( G=\sqrt{y+121}-y+18 \) Find the time when the temperature will be 7 degrees Celsius.

The distance of \( x \) from 0 must be les the 6 Express in the modulus form the following iniqualines - \( -2<2 x<5 \)

B. \( \frac{25 a^{4} b^{2}}{15 a^{4}}= \)

5. If the area of a rectangle is \( x^{2}-x-6 \) sq. units and its length is \( (x-3) \) units, then its breadth is \( \begin{array}{llll}\text { a. }(x-2) \text { units } & \text { b. }(x+3) \text { units } & \text { c. }(x+2) \text { units } & \text { d. }(x-3) \text { units }\end{array} \)

a. \( 6(4-z)=2 z \)

Express in the modulus form the following incqualites \( (x+1)^{2}>9 \)
