2x+3(x+4) = -11

If you can answer this, that would be awesome!! :))

x= -23/5

alternative form:

x= -4.6 or x= -4 3/5

Step-by-step explanation:

2x+3(x+4)= -11

multiply numbers in parenthesis by 3

2x+3x+12= -11

add 2x to 3x

5x+12= -11

move constant to right

5x= -11-12

subtract -11 to -12 but since there both negative the equation is addition.

5x= -23

divide both sides by 5

x= -23/5

alternative form:

x= -4.6 or x= -4 3/5

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.

part a

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y
