Visit $25 allergy shot $8
4a + 1v =57
-2a +1v= 9
I will multiply the second by -1 to cancel v variable (elimination method)
4a +1v =57
2a -1v = - 9
add both
6a. = 48
a= 8
4a= 32
32 + v = 57
v= 25
32+25 = 57
-16 +25=9
Answer:
There is no value of x to fit this requirement.
Step-by-step explanation:
The 2 perimeters in terms of x are:
4(x + 3) for the square and
2(x+1) + 2(x +4) for the rectangle
and these need to be equal so
we equate these 2 and solve for x:
4(x + 3) = 2(x+1) + 2(x +4)
4x + 12 = 2x + 2 + 2x + 8
4x + 12 = 4x + 10
4x - 4x = 10 - 12
0 = -2 which is of course absurd so there is no solution to this equation.
