Show that x=1 is not a solution to 4x+2 2 = 13.​
likoan [24]

Answer:

Replacing x = 1 in the equation above, we have: (4x1) + 22 = 13

=> 5 +22 = 13 => 27 \neq 13

So 27 is not equal to 13 => x=1 is not a solution to 4x+22 = 13.

The perimeter of a rectangular garden is 4534 m. The length is 1125 m more than thrice the width. Find the length and the width
IrinaVladis [17]

Answer:

length = 1696 m

breadth = 571 m

Step-by-step explanation:

perimeter = 4534 m

let breadth be b

so length = b + 1125 m

so

perimeter of rectangular garden = 2(l+b)

4534 m = 2(b+1125m+b) {substituting the value}

or, 4534 m = 2(2b+1125m)

or, 4534 m = 4b + 2250 m

or, 4534 m - 2250m = 4b

or, 2284m = 4b

or, b = 2284m/4

so, b  = 571m

so, l = b + 1125 m

= 571 m + 1125m

= 1696 m
