Answer: 2/5 ÷ 2 = 2/10 as simplified as 1/5 in fraction form. 2/5 ÷ 2 = 0.2 in decimal form.
On number 3 you multiply the number on the outside of the “( )” by the numbers on the inside of the “( )” so 0.5(12m)-0.5(22n)
Number 4 you do the same... 2/3(18x)+2/3(6z) then you multiply those and then add the answers together.
Answer:
Step-by-step explanation:
(-3x + 2)(45x + 21) + (-4x + 25) = 50
-135x^2 - 63x + 90x + 42 - 4x + 25 = 50
-135x^2 + 23x + 67 = 50
-135x^2 + 23x + 67 - 50 = 0
-135x^2 + 23x + 17 = 0
quadratic formula : x = (-b ± √b^2 - 4ac)/2a
a = -135, b = 23, c = 17
x = -23 ± √23^2 - 4(-135)(17) / (2(-135)
x = (-23 ±√9709 )/ -270
x = 23/270 ± 1 / 270√9709/270
x = 0.4501 or x = - 0.2798 <=== these answers are rounded
Answer:
(f - g)(x)= - 6 {x}^{2} - 8x + 9
(f - g)(-4!)= - 55
