Answer:
the answer is 300 + 20 + 7. let me know if this helps!
243 + 62 - 28 = n
n = 305 - 28
n = 277
Answer:
11m8
Step-by-step explanation:
1. add 5m and 6m together
2. multiply 4 and 2
3. pat yourself on the back for solving it!
Applying the rational roots theorem because of the -9 and 4, -3/2 looks like a good bet because -3 is a factor of -9 and 2 is a factor of 4.
Plugging x = -3/2 into the function we have
4(-3/2)^4 + 8(-3/2)^3 - 7(-3/2)^2 - 21(-1.5) - 9 = 0
so -3/2 is a zero
x = 1 and x = -3/4 are not zeroes.
