Answer:
x=40
Step-by-step explanation:
3x-18+x+7+x+9=180
5x-20=180
5x=200
x=40
Answer:94°
Step-by-step explanation:
The sum of the interior angles of the polygon: 180°(n-2)
180°(5-2)=540°
The sum of the interior angles of the pentagon is 540°
So:
P+Q+R+S+T=540°
(4x+2)°+132°+(4x-10)°+(5x-11)°+128°=540°
4x+2+4x-10+5x-11+260=540
13x=299
x=23°
P=4x+2°=4×23°+2°=94°
F(x) = x^2 + 4x - 5
[f(a + h) - f(a)] / h
f(a) = a^2 + 4a - 5
f(a + h) = (a + h)^2 +4(a + h) - 5
= a^2 + 2ah + h^2 + 4a + 4h - 5
f(a + h) - f(a) = a^2 + 2ah + h^2 + 4a + 4h - 5 - ( a^2 + 4a - 5)
---------------- ------------------------------------------------------------
h h
= 2ah + h^2 + 4h h (2a + h + 4) 2a + h + 4
------------------- = ------------------- =
h h
there no table showing mechanic b. but mechanic a charges a one time fee of $50
35 an hour times 5 hours is 175
the total of 225 -175= $50 as a one time fee
12by8=1.5 4by3=1.3 1.5by1.3=1.12
