Answer:
x=9 x=-1
Step-by-step explanation:
2(x-4)^2=50
Divide each side by 2
2/2(x-4)^2=50/2
(x-4)^2=25
Take the square root of each side
sqrt((x-4)^2)=sqrt(25)
x-4 = ±5
x-4 =5 x-4 = -5
Add 4 to each side
x-4+4=5+4 x-4+4 = -5+4
Answer:
£12
Step-by-step explanation:
9.60 = 80% times y.
9.60 = 0.8y
Then, divide each side by 0.8 to get the equation in shape to solve for y.
y = 9.60/0.8
y=12
Answer:
A) area decreases
Step-by-step explanation:
<em>Example:</em> we have a 2 by 3 rectangle with area of 2*3 = 6. If we cut the first dimension in half, then we have a 1 by 3 rectangle that has area 1*3 = 3. The area has decreased. To keep the area the same, we would have to increase the other dimension some specific amount.
