Distribute and simplify the following:
(5m + 6)(m – 7)
(5m + 6)(m – 7) =

Step-by-step explanation:

=((5m+6)(m−7)(5m+6))(m)+((5m+6)(m−7)(5m+6))(−7)

=25m4−115m3−384m2−252m−175m3+805m2+2688m+1764

=25m4−290m3+421m2+2436m+1764

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
