Answer:

Step-by-step explanation:

2x² + 9x = -7

2x² + 9x + 7 = 0

When we multiply we should get 2*7 = 14 and when we add we should get 9. Find the factors of 14 ---> 1,2,7,14. Factors are 2,7 as when we multiply we get 14 and we we add, get 9

2x² + 2x + 7x + 7 = 0

2x( x + 1) + 7 (x + 1) = 0

(x + 1)(2x + 7) = 0

stepan [7]

Answer:

$- 0.62 + 8.35 + 3.9h = - 6.55 + 1.1h \\ \\ 3.9h - 1.1h = - 6.55 + 0.62 - 8.35 \\ \\ 2.8h = - 14.28 \\ \\ h = \frac{ - 14.28}{2.8} \\ \\ h = \frac{ - 142.8}{28} \\ \\ h = - 5.1$

The larger of to numbers is 12 more than the smaller. Their sum is 84. What are the two numbers?

Nataly_w [17]

36 and 48

a = b+12
a+b = 84

(b+12) + b =84
2b +12 = 84
2b = 72
b= 36

a = b + 12
a = 36 + 12
a = 48

Allushta [10]

Answer:

300x^12/15x^10=300/15*x^12/x^10=20*x^2=20x^2

a^4/a^4=1

g^6/g^10=g^-4=1/g^4

so the answer is (20x^2)/g^4
