Please make sure the answer is right I only have 6 questions help?

i told you the answer is -8

all

recall that the inside angles of a triangle add up to 180

Step-by-step explanation:

now add up all the angles and make it equal to 180 :)  

as follows

X+58+45+85 = 180

now use algebra ... and solve for X  :)

X = 180-58-45-85

my calculators tells me

X = -8

what does that answer mean?

it's saying ... like this   58-8    is that angle.. does that help    ? :)

answer: the answer is 40.82

step-by-step explanation: 3.14 x 13(or half of 26) to the power of 2

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

1

4

)=3(6x−9)−8

7x+(8)(x)+(8)(

1

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x

−3
