Answer:
Listen to music or watch a video about what your about to study. Or do what I do... eat while studying
Step-by-step explanation:
There were 30 boys and 10 dogs. 40 heads all together . Then each boy has 2 feet so thats 30*2 = 60 and each dog has 4 feet thats 10*4 = 40 60+40=100 feet
Y = 3.75x...he built 5 desks...so x = 5
y = 3.75(5)
y = 18.75 hrs
Part 1:
(x+30)(x)=1800
<span>x(x+30)=1800
</span>
Part 2:
<span>x+30)(x)=1800</span>
Distribute the x.
<span><span>x2</span>+30x=1800</span>
Subtract 1800 from both sides.
<span><span><span>x2</span>+30x−1800=0</span></span>
