Answer:

51i + 48j

Explanation:

Let's simplify step-by-step.

12(3i+7j)+3(5i−12j)

|Which is the equation.|

Distribute:

=(12)(3i)+(12)(7j)+(3)(5i)+(3)(−12j)

=36i+84j+15i+−36j

Combine Like Terms:

=36i+84j+15i+−36j

=(36i+15i)+(84j+−36j)

=51i+48j

Answer:

=51i+48j

I hope this helps, if it doesn't then just message me and ill be more than happy to help :)

Answer:

Get practicing early

ALOT of practice tests

Learn what you are missing everytime you take a test

There's different strategies for the reading section (like reading first and last sentence of each paragraph and many more) there's many other strategies google them!

Goodluck!

I liked SAT more than ACT just saying if you have the option to take either take both practice tests to determine which one you might score more

find the area under the curve first
\int\limits^{\sqrt[3]{\pi}}_0 {x sin(x^3)} \, dx =0.61157809233184
then solve c∛π=0.61157809233184
c≈0.41757577488026
round if necicary

alright, solve where they itnersect

x²=y=mx
x²=mx
x²-mx=0
x(x-m)=0
set to zero

x=0

x-m=0
x=m

they intersect at x=0 and x=m

which one is on top?
hmm
y=mx will always be on top (I don't know how to prove that but it's on top)

so we do
\int\limits^m_0 {mx-x^2} \, dx =8
solve
\int\limits^m_0 {mx-x^2} \, dx =[\frac{mx^2}{2}-\frac{x^3}{3}]^m_0  (\frac{m(m)^2}{2}-\frac{m^3}{3})-(0)=\frac{m^3}{2}-\frac{m^3}{3}=\frac{m^3}{6}=8

so
\frac{m^3}{6}=8
m³=48
m=2∛6
