8 + 6t - 3t + t would equal 12t^3? First one gets Brainliest Answer!
Answers
8 + 3t + t = 12t³
8 + 4t = 12t³
-12t³ + 4t + 8 = 0
-4(3t³) - 4(t) - 4(2) = 0
-4(3t³ - t - 2) = 0
-4 -4
3t³ - t - 2 = 0
3t³ + 3t² - 3t² + 2t - 3t - 2 = 0
3t³ + 3t² + 2t - 3t² - 3t - 2 = 0
t(3t²) + t(3t) + t(2) - 1(3t²) - 1(3t) - 1(2) = 0
t(3t² + 3t + 2) - 1(3t² + 3t + 2) = 0
(t - 1)(3t² + 3t + 2) = 0
t - 1 = 0 or 3t² + 3t + 2 = 0
+ 1 + 1 t = -(3) ± √((-3)² - 4(3)(2))
t = 1 2(3)
t = -3 ± √(9 - 24)
6
t = -3 ± √(-15)
6
t = -3 ± i√(15)
6
t = ⁻¹/₂ ± ¹/₆i√(15)
t = ⁻¹/₂ + ¹/₆i√(15) or t = ⁻¹/₂ - ¹/₆i√(15)
Solution Set: {1, ⁻¹/₂ ± ¹/₆i√(15)}

Answer:
tan theta = -4/3.
Step-by-step explanation:
The inequality means that theta is in the 4th quadrant ( between 270 and 360 degrees.
The angle whose sine is 4/5 is 53.13 degrees.
So the angle whose sine is -4/5 is 306.87 degrees.
The tangent is negative and the triangle formed by the angle in the 4th quadrant has sides 3, - 4 and 5 ( by the Pythagoras theorem).
So tan theta = opposite / adjacent = -4/3 (answer).

perm=2 times haircut
she also needs 5 dollars for lunch
so therefor if 95 is enough to cover it we do
cost=lunch+perm+haircut
cost=5+perm+haircut
subsitute
95=5+2 times haircut+1 time haircut
add like terms
95=5 +3 times haircut
subtract 5 from both sides
90=3 times haircut
diide by 3
30=haircut
subsitute
perm=2 times haircut=2 times 30=60
perm=$60

Answers
B. According to image
Students which are in neither = 154 -72 -35 + 20

What is the product of two algebraic expressions?
When two algebraic expressions are multiplied, the result is called the product, and the two expressions making up the product are called factors and multiplicands.
The multiplication of two algebraic equations can be expressed as a × b.
The product of 3a + 5 and 2a2 + 4a – 2 is determined in the following steps given below.
Hence, the product of 3a + 5 and 2a2 + 4a – 2 is .

Answer:
6a3 + 22a2 + 14a - 10
Step-by-step explanation:
(3a + 5) x (2a^2 + 4a - 2)
= 3a(2a^2 + 4a - 2) + 5(2a^2 + 4a - 2)
= 6a^3 + 12a^2 - 6a + 10a^2 + 20a - 10
= 6a^3 + 22a^2 + 14a - 10
