Answer:
(b) t-4 and t not equal 8
Step-by-step explanation:

Answer:
B. (b x d) - c
Step-by-step explanation:
i. -(a x d) + b
= -(6 x
) + 8
= -3 + 8
= 5
ii. (b x d) - c
(8 x
) - 4
= 4 - 4
= 0
iii. 2(b x f) + a
= 2(8 x
) + 6
= 4 + 6
= 10
iv. (a x e) - c
= (6 x
) - 4
= 2 - 4
= -2
Thus, the expression which is equivalent to 0 is that of option B.
A is (-1,0) B is (0,-3) C is line of symmetry D is (3,0) E is (2,-3) F is (1, -4)
3 n
- = -
4 10
cross multiply to get 4n=(3)(10)
multiply 3 and 10. 4n/4 = 30/4
n = 7.5
Just use the formula 1/2bh
