Answer:

DE = 10

Step-by-step explanation:

Here, we want to find the value of DE

we use the intersecting chord principle

That will be;

CE * ED = AE * BE

we have;

6 * DE = 5 * 12

DE = (5 * 12)/6

DE = 5 * 2

DE = 10

2m - 6 = 8m then 3m =

Mashcka [7]

2m - 6 = 8m
2m - 6 - 2m = 8m - 2m
2m - 2m - 6 = 8m - 2m
-6 = 6m
-6/6 = 6m/6
-1 = m
-1(3) = m(3)
-3 = 3m
3m = -3

A baseball team won 8 games and lost 6. If the team continues at this ratio, how many wins will the team have after playing 21 g

DIA [1.3K]

Answer:

Identify all of the root(s) of g(x) = (x2 + 3x - 4)(x2 - 4x + 29)

vichka [17]

Answer:

x=-4,1,2+5i,2-5i

Step-by-step explanation:

Given is an algebraic expression g(x) as product of two functions.

Hence solutions will be the combined solutions of two quadratic products

$g(x) = (x^2 + 3x - 4)(x^2 - 4x + 29)\\$

I expression can be factorised as

$(x+4)(x-1)$

Hence one set of solutions are

x=-4,1

Next quadratic we cannot factorize

and hence use formulae

$x=\frac{4+/-\sqrt{16-116} }{2} =2+5i, 2-5i$
