Answer:
180 = 150m + c
177.25 mm
Step-by-step explanation:
L = mT + c
180 = m(150) + c
180 = 150m + c
c = 180 - 150m
181.5 = 210m + c
181.5 = 210m + 180 - 150m
1.5 = 60m
m = 0.025
c = 180 - 150(0.025)
c = 180 - 3.75
c = 176.25
L = 0.025T + 176.25
T = 40
L = 0.025(40) +176.25
L = 177.25 mn
1 because you replace x with 2 so, (2)squared -5x2 + 7 = 4 - 10 + 7 = 1
Answer:
x^2 +3x+2
Step-by-step explanation:
the question has been a bit expanded so this is what you should do next
x(x+1) +2(x+1) i used the figures in the first bracket to multiply the second bracket
then use the figures outside the bracket to multiply what is inside i.e
x×x =x^2 and so on that gave me
x^2 +x+2x+2 =x^2 +3x because there's like an invisible 1 +2
