1. <span><span>Какое из</span><span>уравнений</span><span>соответствует</span><span>задачи</span><span>:</span><span>Произведение</span><span>двух</span><span>чисел равна</span><span>135.</span><span>Найдите эти</span><span>числа, если</span><span>одно из них на</span><span>6</span><span>больше другого</span><span>?</span></span>
<span><span>А) х * 135= х + 6 </span></span>
<span><span>Б) х+( х + 6) = 135 </span></span>
<span><span>В) х ( х+6)= 135</span></span>
<span><span>Г) х - ( х+6 ) = 135</span></span>
<span><span>2. </span></span><span><span>Составьте</span><span>уравнения</span><span>по условию</span><span>задачи </span><span>:</span><span>Половина</span><span>периметра</span><span>прямоугольника равна</span><span>10</span><span>м</span><span>,</span><span>а площадь</span><span>прямоугольника</span><span>-</span><span>21</span><span>м2.</span></span>
<span><span>А) х ( 10 - х ) = 21</span></span>
<span><span>Б) х + ( 21 - х ) = 10 </span></span>
<span><span>В) х * ( 20 - х ) = 21</span></span>

<span><span>Б) 70 70
</span></span>
<span><span> ___ - ___ = 12
</span></span>
<span><span> х-1 х+1 </span></span>
<span><span>В) ( х - 1 ) * 12 = 70 </span></span>
