Answer:
No solution
Step-by-step explanation:
Absolute value of 2x would be unsolvable, as the absolute value
cannot be negative.
-2(1-7n)-5n=34
Multiply the bracket by -2
(-2)(1)=-2
(-2)(-7n)=14n
-2+14n-5n=34
-2+9n=34
Move -2 to the other side. Sign changes from -2 to +2.
-2+2+9n=34+2
9n=34+2
9n=36
Divide by 9 for both sides
9n/9=36/9
n=4
Answer: n=4
Answer:
-5
Step-by-step explanation:
The axis of symmetry is the x- axis of the vetex.
Solution:
we have given the length of the rectangular card-

and, width-

now, the area of the card will be- length×width.
so, we have-

we also have given the length of ribbon-

and, width-

so, area of the ribbon is-
length×width

now the area of shaded gray region will be-

Hence, the required expression would the above expression.
0
