A=30^2+ 2 x 30 x 26
A= 900 + 1560
A= 2460
so the surface area is 2460
v=1/3 x 30^2 x 26
v=1/3 x 900 x 26
v= 300 x 26
v=7800
so the volume is 7800
and the way the order of operations helped you is that you had to remember to always do the exponents before any of the other multiplication
Answer:
Yes! it is there are straight across from each other and will never touch Hope I helped!
Answer:
Step-by-step explanation:
Use the FOLD method<span>
(a+b)(c+d)=ac+ad+bc+bd
</span><span>−12<span>s<span><span>^2 </span><span></span></span></span>+ 3st + 8ts − 2<span>t<span><span>^2</span><span>
</span></span></span></span>Collect like terms
-12{s}^{2}+(3st+8st)-2{t}^{2}
Simplify
<span>-12{s}^{2}+11st-2{t}^{2}<span>−12<span>s<span><span>2</span><span></span></span></span>+11st−2<span>t<span><span>2
The answer is = -12s^2 + 11st - 2t^2</span></span></span></span></span>
Hey there! :D
Slope intercept form: y=mx+b
4x-2y=9
Add 2y to the other side.
4x=9+2y
Subtract 9 on both sides.
4x-9=2y
Flip the equation over.
2y=4x-9 <== slope intercept form
I hope this helps!
