Answer:
<em>The answer is (3)</em>
Step-by-step explanation:
32x+(3) - 107x4 and the 3 is close.
therefor is it is (3)
Step-by-step explanation:
1×100000+2×10000+9×1000+9×100+8×10+2×1
=100000+20000+9000+900+80+2
Let the base be b. Then the height is b-4. So:
1/2(b)(b-4)=6
b²-4b-12=0
(b-6)(b+2)=0
b=6
b-4=2
