I would go with -33 cause if you replace the t with -33 you would have to solve the problem and it would be 7 so -33 is the answer.
Answer:
area=38cm²
perimeter=34cm
Step-by-step explanation:
I found three shapes and got
4·2=8
3·3=9
9·3=21
8+9+21=38cm²
5+6+9+4+3+2+2+3=34
Step-by-step explanation:
12(6) - 7(2) + (6-3)
48 - 14 + 2
36
Factor the following:
12 x^4 - 42 x^3 - 90 x^2
Factor 6 x^2 out of 12 x^4 - 42 x^3 - 90 x^2:
6 x^2 (2 x^2 - 7 x - 15)
Factor the quadratic 2 x^2 - 7 x - 15. The coefficient of x^2 is 2 and the constant term is -15. The product of 2 and -15 is -30. The factors of -30 which sum to -7 are 3 and -10. So 2 x^2 - 7 x - 15 = 2 x^2 - 10 x + 3 x - 15 = x (2 x + 3) - 5 (2 x + 3):
6 x^2 x (2 x + 3) - 5 (2 x + 3)
Factor 2 x + 3 from x (2 x + 3) - 5 (2 x + 3):
Answer: 6 x^2 (2 x + 3) (x - 5)
Answer:
0
Step-by-step explanation:
2 + 2 = 4 and then 4 - 4 = 0
