Answer:
x = -2
x = -10
Step-by-step explanation:
<u>Step 1 :</u><u> Rearrange</u>
x² + 12x + 20 = 0
<u>Step 2:</u><u> Factorise</u>
(x + 2)(x + 10)
<u>Step 3:</u><u> Find the roots / values of x</u>
Make each bracket equal zero.
(x + 2) = x = -2
(x + 10) = x = -10
Hope this helps!
Set up the equation like this
4,275= x (1.025)∧18
then solve for the answer
The answer should be $2740.98, but you should double check.
Answer: 78 pizzas
Step-by-step explanation:
65/10=6.5=10%

Answer: 0.6kg of flour will be in each batch of scones.
Step-by-step explanation:
Adam has 16.45 kg of flour, and he used 6.4kg to make hot cross buns. This means that the remaining flour would be the total amount of flour that he had initially minus the the amount that he used to make hot cross buns. This is expressed as
16.5 - 6.4 = 10.05 kg
The remaining flour is exactly enough to make 15 batches of scones. This means that 10.05 kg of flour will be enough to make 15 batches of scones.
We want to determine how much flour, in kg, will be in each batch of scones. Let this amount of flour be xkg
If 10.05 kg of flour will be used to make 15 batches of scones. Then,
xkg of flour will be used to make 1 batch if stones
x = 10.05/15
x = 0.67
Answer:
Step-by-step explanation:
hello :
let : Z1 = 2-4i Z2 = 6+i
the distance between Z1 and Z2 is :
/Z2 - Z1 / = /(6+i)-(2-4i)/ =/4+5i/ = √(4²+5²) =√41
