Answer:
a battery costs £0.43
Step-by-step explanation:
<u>Set up an equation</u>
11b+b+4.84=10
S<u>ubtract 4.84 from both sides</u>
12b+4.84=10
-4.84=-4.84
12b=5.16
<u>Divide 12 on both sides</u>
b=5.16/12
b=0.43
I THINK you just multiply them all together

Answer:
(7x+5)(7x-5)
Step-by-step explanation:
We can use the difference of squares equation which states that when a number is multiplied like: (ax+b)(ax-b) then it equals (ax-b). In this equation, since there is no "b" in the typical ax^2+bx+c, we can recognize that the answer is not a square, but a difference of squares.
