Answer:
If the roots of any equation are equal then it means that their Discriminant = 0
So, b²-4ac = 0
We have given the equation 2x² + kx + 2, where,
a = 2
b = k (we have to find the value)
c = 2
Then, b²-4ac=0
b² - 4(2)(2) = 0
b² - 16 = 0
b² = 16
√16 = 4
Hence the vue of k is 4.

Answer:
The baker bought 8 pounds of apples and 4 pounds of bananas.
Step-by-step explanation:
a+b=12.
0.75a+1.05b=10.20
First, multiply 2 my 10.
75a+105b=1020.
Then multiply 1 by 75.
75a+75b=900.
Then subtract.
75a+105b=1020
75a+75b=900.
75a-75a+105b-75b=1020-900
30b=120
b=4
Substitute into (1)
a+4=12
a=8.
Hope this helps :)
