Thats simple!
h(x)= \frac{x^{2}+3x }{4x+27}
find h(-8)
All we need to do is PLUG IN THE -8
h(-8)= \frac{(-8)^{2}+3(-8) }{4(-8)+27}
        =\frac{64-24}{-32+27} (negative²=positive,                                                                                negative×positive=negative)
        =\frac{40}{-5}
h(-8)=-8

Please help with these 4 questions
horsena [70]

We use the BODMAS method to solve the given questions.

Solve the Bracket then Divide Multiply Add and Subtract

1. 32÷4×(16×1/2) - 2

= 32÷4 × ( 8 ) - 2

= 8 × 8 - 2 = 64 - 2 = 62

2. 20 ÷ (5×2/5) + 3

= 20 ÷ (2) + 3 = 20 ÷ 2 + 3

= 10 + 3 = 13

3. 1/2 ×(6×4) ÷ 3 + 2

= 1/2 × 24 ÷ 3 + 2

= 1/2 × 8 + 2

= 4 + 2 = 6

4. 2 (6÷2+8) - 4

= 2 (3+8) - 4

= 2 × 11 - 4

= 22 - 4

= 18
