The ratio table below shows the relationship between the number of bricks in a wall and the length of the wall.
when the number of bricks is multiplied by 2, the length is multiplied by
a) 1.
b) 2.
c) 3.
d) 6.

When number of bricks is multiplied by 2, the length is multiplied by

B) 2

Step-by-step explanation:

Number of bricks is two times the length of the wall

i.e. Number of bricks= 2×Length of the wall

When the number of bricks is multiplied by 2, the length is also multiplied by 2

since, when number of bricks=6 then, length of wall=3

and when number of bricks=2×6=12 then, length of wall=2×3=6

Hence, when number of bricks is multiplied by 2, the length is multiplied by

B) 2

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
