6. The area of a rectangular field is given by the trinomial t2 – 4t – 45. The length of the rectangle is t + 5. What is the expression for the width of the field? (1 point)
t – 9
t – 5

Respuesta :

2. Your answer is (x + 3)(x + 8) because 8 and 3 add up to 11 and are also factors of 24.

3. Your answer is (m + 10)(2m + 7), because 7 × 10 = 70 and, when 10 is multiplied by 2 because of 2m, 20 + 7 = 27

4. This is the difference of two squares because 64 is a square number, so your answer is (g + 8)(g - 8)

5. Your answer is (7t + 3)(7t - 3)

6. If you factorise that expression, the width would be the bracket that isn't (t + 5), so:
(t + 5)(t - 9)
So the width is t - 9

I hope this helps!
