Answer:Example 1.
2x2 - 5x - 12 = 0.
(2x + 3)(x - 4) = 0.
2x + 3 = 0 or x - 4 = 0.
x = -3/2, or x = 4.
Step-by-step explanation:
Answer:
18x
Step-by-step explanation:
Rewrite, 324x² as 18x².
= √18x²
Pull terms out from under the radical, assuming positive real numbers.
18x
Answer: an average of 13.5 mph is very respectable
Step-by-step explanation:
Hello.
<span>Reorder the terms:
-6 + y = 4(x + 5)
Reorder the terms:
-6 + y = 4(5 + x)
-6 + y = (5 * 4 + x * 4)
-6 + y = (20 + 4x)
Solving
-6 + y = 20 + 4x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '6' to each side of the equation.
-6 + 6 + y = 20 + 6 + 4x
Combine like terms: -6 + 6 = 0
0 + y = 20 + 6 + 4x
y = 20 + 6 + 4x
Combine like terms: 20 + 6 = 26
y = 26 + 4x
Simplifying
y = 26 + 4x

If Adam has 16.45 kg of flour and he uses 6.4 kg to make hot cross buns, then he has left
16.45 - 6.4 = 10.05 kg of flour.
If Adam wants to use the remaining flour to make 15 batches of scones, then each batch of scones requires
10.05 : 15 = 0.67 kg of flour.
Answer: each batch of scones requires 0.67 kg of flour.
