Answer:

x=3, -5.

Step-by-step explanation:

x^2+2x+25=40

x^2+2x+25-40=0

x^2+2x-15=0

factor out the trinomial,

(x-3)(x+5)=0

zero property,

x-3=0, x+5=0,

x=0+3=3,

x=0-5=-5.

Which number line correctly shows –0.8 + 0.6? A number line going from negative 1.6 to positive 1.6. An arrow goes from negative

Phoenix [80]

Answer:

Hi there, are you sure you didn't forget any parenthesis or signs? I can't find the right answer in the options, the one that would end up at -0.2 in the end I can edit my answer if you tell me some additional option or info about the expression I need to show on the number line

Step-by-step explanation:

which number line shows correctly -0.8 + 0.6?

well lets write it in words minus eight tenths plus six tenths\

so minus:

you go 0.8 units to the left from 0,

then plus:

you go 0.6 units right from -0.8, getting to -0.2

since there is no exact answer like that we can rearrange the addends 0.6-0.8, now:

we go from 0 6 tenths units to the right and get to 0.6, then we go from 0.6 eight tenths unit to the left to get to -0.2

13-5m=4-6m show work please

Vesna [10]

First subtract 4 from both sides
$13 - 4 - 5m = - 6m$

then simplify
$9 - 5m = - 6m$

add -5 to both sides
$9 = - m$

since a variable shouldn't be negative the answer should be
$m = - 9$

(I prefer having the variable on the left side)
