2)24=2³×3 ; 40=2³×5 ; c.m.m.m.c=2³×5×3 ; c.m.m.m.c=120 ;
3)-3-x=4 ; -x=4+3 ; -x=7 ; x=-7 ;
[tex]4)A = \pi \: R {}^{2} = 36\pi[/tex]
[tex]36 = R {}^{2} [/tex]
[tex]R = \sqrt{36} [/tex]
[tex]R = \: cm[/tex]
[tex]D = 2 \times r = 2 \times 6 = 12[/tex]
[tex]5)Al = \frac{pb \times ap}{2} [/tex]
[tex]Al = \frac{12 \times 40}{2} [/tex]
[tex]Al = 240 \: cm {}^{2} [/tex]
