Answer:
t² + t - 3 = 0
Step-by-step explanation:
C = t - 5
B = t² - 2
2C + 2B
= 2(t - 5) + 2(t² + 2)
= 2t - 10 + 2t² + 4
= 2t² + 2t - 6
=> t² + t - 3 = 0
50. since n_1/4<1 the equation is not true. it has no solution.
48. same thing since 45 <= z the equation is not true.
9 less means subtract
the product of 5 and the number n mea multiply 5 and n
D. 5n-9
We want to simplify this as much as possible. 11/110=1/10 since 110=11*10. Therefore, the answer is 0.1
