Factorise 3(x+2)^2-10(x+2)+3
Answers
Let's substitute (x + 2) with a:
3(x + 2)² - 10(x + 2) + 3 = 3a² - 10a + 3 =
= 3a² - 9a - a + 3 =
= 3a * a - 3a *3 - (a - 3) =
= 3a(a - 3) - (a - 3) =
= (a - 3)(3a - 1)
Now, substitute a with x + 2:
(a - 3)(3a - 1) = (x + 2 - 3)(3(x + 2) - 1) =
= (x - 1)(3x + 6 - 1) =
= (x - 1)(3x + 5)

Answer:
y = -5x + 6
Step-by-step explanation:
y = 1/5 x + 4/5
so that two lines are perpendicular, its slope must be opposite and reciprocal
y = m x + b
m: slope perpendicular -1/m
if our formula is y = 1/5 x + 4/5
m = 1/5
so the slope of our new formula will be
m' = -5/1
m' = -5
now if you tell us that you have to go through a certain point (1/1)
we just have to replace the values in the following formula and solve
y - y1 = m ( x - x1)
y - 1 = -5 ( x - 1)
y = -5x + 5 + 1
y = -5x + 6

Answer:
375 grams of soup sir I hope this helps
Final answer:
Tania has a total of 585 grams of soup before she warms it on the stove. This is found by adding the weight of all the ingredients she used: water (225g), condensed soup (300g), celery(50g), and carrots(10g).
Explanation:
The subject of this question is about adding quantities, which falls under Mathematics. Tania combines multiple ingredients to make soup. She uses 225 grams of water, 300 grams of condensed soup, 50 grams of celery and 10 grams of carrots. To find out the total amount of soup she has before warming it up, you simply need to add up all these amounts. So, 225g (water) + 300g (condensed soup) + 50g (celery) + 10g (carrots) = 585 grams. Therefore, Tania has 585 grams of soup before she warms it up on the stove.
