factorise (5a²-25a+20)÷(a-1) class 8​

Answers

Answer 1

Answer:

[tex]5(a-4)[/tex]

Step-by-step explanation:

[tex]\frac{(5a^{2} -25a+20)}{ (a-1)}\\=\frac{5(a^{2} -5a+4)}{ (a-1)}\\\\=\frac{5(a-1)(a-4)}{ (a-1)}\\=5(a-4)[/tex]

Answer 2
(5a²-25a+20) ÷ (a-1)

= 5(a²-5a+4) ÷ (a-1)

= 5(a-1)(a-4) ÷ (a-1)

= 5(a-1)(a-4) / (a-1)

{ (a-1) is crossed out }

= 5(a-4)

Hope it helps!

Answers

Answer:

1. Well, to cross multiply them you multiply the numerator in the first fraction times the denominator in the second fraction, then you write that number down. ... The reason we cross multiply fractions is to compare them. Cross multiplying fractions tells us if two fractions are equal or which one is greater.

2. Cross multiplying fractions to find a missing numerator or denominator for equivalent fractions works because it is a shortcut for rearranging to isolate the variable.

3x + 7 = -11

how do I solve for x?

PLEASE HELP - URGENT!!

Answers

Ok you minus 7 from both sides so it’s 3x = -18 then you divide 3 from the problem on both sides then ur left with x=-6

Answer:

x= -6

Step-by-step explanation:

3x + 7 = -11

3x = -18 (By doing - 7 from both sides)

x= -18/3 (By dividing by 3 from both sides)

x= -6 (-18 divided by 3 is equal to -6)

Confirmation:

3(-6) + 7 = 11

-18 + 7 = -11 (Correct)

If the points (2, 4), (5, k), and (8, 20) are on the same line, what is the value of k?

Answers

Answer:

k = 12

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (2, 4) and (x₂, y₂ ) = (8, 20)

m = [tex]\frac{20-4}{8-2}[/tex] = [tex]\frac{16}{6}[/tex] = [tex]\frac{8}{3}[/tex]

Repeat using (5, k) as one of the points and equate to [tex]\frac{8}{3}[/tex]

(x₁, y₁ ) = (2, 4) and (x₂, y₂ ) = (5, k) , then

m = [tex]\frac{k-4}{5-2}[/tex] = [tex]\frac{k-4}{3}[/tex] = [tex]\frac{8}{3}[/tex] ( cross- multiply )

3(k - 4) = 24 ( divide both sides by 3 )

k - 4 = 8 ( add 4 to both sides )

k = 12
