So triangles have 180 degrees total and you have the measure of two angles so you can solve for the third.
T + 41+ 90= 180 add together 41 and 90
T + 131 =180 subtract 131 from 180
T = 49
So the measure of angle T is 49 degrees

Solve the equation !!!! HELP PLEASE

Answer:

x=-1/2

Step-by-step explanation:

Given:

8x^3+12x^2+6x+1=0

Making factors of the given polynomial by using cube formula, given as

(a + b)^3 = a^3 + 3a^2b + 3ab^2 + b^3

Re-writting the given polynomial:

(2^3.x^3) + 3(2^2.x^2)(1)+3(2x)(1) + (1^3)=0

Hence (2^3.x^3) + 3(2^2.x^2)(1)+3(2x)(1) + (1^3) can be written as (2x+1)^3

(2x+1)^3= 0

2x+1= 0

2x= -1

x= -1/2 !

What is the sun of p and q ?
marusya05 [52]
Since it is linear, we can find a linear equation to represent the relationship.  We have two points (3,6) and (11,15).  The slope is 9/8.  So we have an equation:

y = (9/8)x + b

Plug in (3,6) to find out that b = 21/8
So our equation that represents this linear relationship is:

y = (9/8)x + 21/8

Now to figure out what "p" is, we plug in x = -1, and we get p = 1.5
To figure out what "q" is, we plug in x = 7, and we get q = 10.5

Therefore the sum of p and q:
1.5 + 10.5 = 12
