4t ^ 2 - 16 ÷8 ÷ t - 2 ÷6
=(4t ^ 2)-(16 ÷8 ÷ t)-(2 ÷6)
=(4t ^ 2)-(2/t)-1/3
=4t ^ 2-2/t-1/3
Answer:
Step-by-step explanation: The volume of the grain silo can be found by adding the volumes of all the solids of which it is composed (a cylinder and two cones). The silo is made up of a cylinder (with height 10 feet and base radius 5 feet) and two cones (each with height 5 ft and base radius 5 ft). The formulas given at the beginning of the SAT Math section:
Volume of a Cone:
Volume of a Cylinder:
can be used to determine the total volume of the silo. Since the two cones have identical dimensions, the total volume, in cubic feet, of the silo is given by
which is approximately equal to 1,047.2 cubic feet.
<u>The final answer is D.</u>
Answer: undefined in both cases.Explanation:1) Expression to evaluate:

2) You are asked to evaluate that expression for two different cases,
x = 0 and x = 3.3) First case:
x = 0The expression cannot be evaluated at x = 0, because the
denominators (both denominators)
equal 0, and the division by 0 is not defined.
So, the answer is
undefined.
4) Second case,
x = 3When you replace x = 3 you get:

Again, this result in a
division by 0, so you conclude that it is
undefined too.
Terms are 3x, 5, 2x, and x.
Like terms are 3x and 2x.
Coefficients are 3 and 2.
Constant is 5.
lmk if anything is incorrect!!
