X/7-4=-2 u add two to both sides
x/7-2=0you add two to both sides again
x=14 u multiplied 7 and 2 and by x
Answer:
x = 5
Step-by-step explanation:
y = -4x + 5 4x + y = 10
substitute the y in the second equation with
(-4x +5).
4x + (-4x + 5) = 10 then add like terms.
x + 5 = 10 solve for x.
10 - 5 = 5 make sure to check your answer.
5 + 5 = 10
diagonal = 9√2 ≈ 12.73
the diagonal splits the square into 2 right triangles with the hypotenuse being the diagonal of the square
using Pythagoras' identity
d = √(9² + 9²) = √162 = 9√2 ≈ 12.73 ( to 2 dec. places )
