Solve the simultaneous equations:<br><br> 3a-2b=14 <br> 12a+9b=39

kirill [66]

Use elimination
Multiply first equation by 4
12a - 8b = 56
12a + 9b = 39
Subtract both
-17b = 17
b = -1
Plug in -1 for b
3a - 2(-1) = 14
3a = 12, a = 4
Final answer: a = 4, b = -1

Divide. HELP ASAP PLEASE!!

VashaNatasha [74]

Answer:

The answer to your question is below

Step-by-step explanation:

a) $\frac{s^{2}- 3s - 28 }{s - 7}$

Factor the numerator is a polynomial of the form x² + bx + c

s² - 3s - 28 = (s - 7)( s + 4)

Substitute

$\frac{(s - 7)(s + 4)}{(s - 7)}$

Simplify like terms

Result s + 4

b) $\frac{c^{2} + 5c - 24}{c + 8}$

Factor the numerator is a polynomial of the form x² + bx + c

c² + 5c - 24 = (c + 8)(c - 3)

Substitute

$\frac{(c + 8)(c - 3)}{c + 8}$

Simplify like terms c - 3

Result c - 3
