5 less than x is eight
x-5 = 8
two more than three times x = 17
2 + 3x = 17
Sum of triangle angles = 180
3x + 3x+8 + 9x+7 = 180
Then solve for x then if 3x +8 + 139 = 180 (straight line) then the lines are parallel
2x = 180 - 74 - 48 (Image is very blurry....that might be 43 or 48)
x = 29
Subtract 6 from both sides of the equation to get:
16 = 4x now divide both sides by 4
4 = x
x=4
5x-2 = 28 add 2 to both sides of the equation
5x = 30 now divide both sides 5
x = 6
4x^2-8x+3=
(2x-1)(2x-3) = area
then perimeter would be 2 [(2x-1) + (2x-3)] = 2 (4x-4) = 8x-8
I'll do the third one
Fo = 9/5 C + 32
Fo = 9/5 ( 15) + 32
Fo = 59 o when Co = 15o
Just put in ' 0 ' for C and calculate F
then put in 5 for C and calculate
etc.....
Wow, quite the echo here on the forum !
You didn't post anything to be converted
Fo = 9/5 Co + 32
