Which relationship is always correct for the angles p, q, and r of triangle ABC?

1 answer:

8 0

The correct answer is "D".

q+r=p

Because the missing angle would equal 180-q-r, it would be the same as p. The one angle (the unmarked) is supplementary to the missing angle. (180 degrees)

I hope this helps!

Use distributive property to rewrite problem so it had only two factors. Then solve (25x9)+(75x9)=

Shalnov [3]

ANSWER

$(25\times9)+(75\times9)=9(25+75)$

$(25\times9)+(75\times9)=9(100)$

$(25\times9)+(75\times9)=900$

EXPLANATION

According to the distributive property,

$(a\times b)+(a\times c)=a(b+c)$

This implies that,

$(25\times9)+(75\times9)=9(25+75)$

$(25\times9)+(75\times9)=9(100)$

The Right Hand Side of the equation now has 2 factors.

We solve now to obtain;

$(25\times9)+(75\times9)=900$
