The length of the diagonal of the square is 22.05 units
<h3>How to find the diagonal of a square?</h3>
A square have all its sides equal to each other.
Therefore, using Pythagoras theorem,
c² = a² + b²
c² = (9√3)² + (9√3)²
c² = 81 × 3 + 81 × 3
c² = 243 + 243
c² = 486
square root both sides
c = √486
c = 22.045407685
c = 22.05 units

Hello,
Answer C
y=2x-3.5==>2x-7=3.5 (1)
x-2y=-14 (2)
(1)-2*(2)==>3y=28+3.5 ==>y=31.5/3==>y=10.5
x=-14+2*10.5==>x=7
sol={(7,10.5)}
Answer: -10.6
Step-by-step explanation: -3|z| + 2(a + y) =
= -3|-4.2| + 2(-2 + 3)
= -3(4.2) + 2(1)
= -12.6 + 2
= -10.6
Idk if this was right but i was kinda confused by the question.
