3/2.5 = 48/c
Cross multiply
3*c = 3c
2.5 * 48 = 120
3c = 120
3c/3 = 120/3
c= 120/3
c= 40

X² - 169 = 0
x = ?
<span> Add 169 to both sides.
</span>
x² <span>− 169 + 169 </span>= <span>0 + 169</span>x² = 169
Square root
x = <span>± <span>√<span>169
</span></span></span>
<span><span>x = <span><span>13<span> or </span></span>x </span></span>= <span>−13
x can be 13 or -13.</span></span>
