-4+-12-15 =-7

So we know -4 is j so when you put -4 then -12 will be h and then 15 will be k and then when you put them together it will -7

Solve (x + 1)2 – 4(x + 1) + 2 = 0 using substitution. u = Select the solution(s) of the original equation.

Semenov [28]

(x - 1)2 - 4(X + 1) + 2 = 0

2x - 2 - 4x - 4 + 2 = 0

(2x - 4x) - 4 = 0

-2x = 4

x = 4/-2

x = -2

Given

$\left[\begin{array}{ccc}-2&3\\2&4\\\end{array}\right]$ + $\left[\begin{array}{ccc}3&1\\-1&2\\\end{array}\right]$

Add corresponding elements to obtain the sum, that is

= $\left[\begin{array}{ccc}-2+3&3+1\\2-1&4+2\\\end{array}\right]$

Can someone help me with this

Morgarella [4.7K]

Answer:

FG=30

Step-by-step explanation:

Since we know that Point G is on the Segment FH, it doesn't really matter where G is, but we can know for certain that:

$FH=FG+GH$

We are given that FH is 4x, GH is x, and FG is 2x+10. Substitute:

$4x=(2x+10)+x$

Solve for x. On the right, combine like terms:

$4x=3x+10$

Subtract 3x from both sides:

$x=10$

So, the value of x is 10.

To find the value of FG, substitute 10 into its x:

$FG=2x+10\\FG=2(10)+10$

Multiply:

$FG=20+10$

Add:

$FG=30$

And we're done!
