Serhud [2]3 years ago

Answer:

x = - 10, x = 6

Step-by-step explanation:

Given

(x + 2)² = 64 ( take the square root of both sides )

x + 2 = ± \sqrt{64} = ± 8 ( subtract 2 from both sides )

x = - 2 ± 8

Thus

x = - 2 - 8 = - 10

x = - 2 + 8 = 6

6 sweets cost 42p altogether how much do 8 sweets cost
Eddi Din [679]
The best thing to do is to find the cost of one sweet, and to do this, divide 42 by 7.
42/7= 6
Therefore, one sweet costs 6p.
To find the cost of 8 sweets, you've got to multiply 6 by 8, and this gives you 54p.
Therefore, 8 sweets cost 54p
This is basically just finding unit rate and multiplying.

Round 0.198 to three decimal places
Crazy boy [7]
.198 is already rounded to three decimal places. If it had a number after the 8 that was greater than 5, it would be rounded to .199, though
