Answer:
Am = 1500 cm²
Step-by-step explanation:
If you mean leg around the right angle a = 3 cm and b = 5 cm then :
Formula for calculating area of the right triangle is:
A = a · b / 2 since we have 200 triangles, area of the mosaic is:
Am = 200 · A = 200 · a b / 2 = 200 · 3 · 5 / 2 = 1500 cm²
Am = 1500 cm²

Answer:
(x, y) =(-6,4)
Step-by-step explanation:
3x-y=-28
-5x-4y=-10
y=3x+28
-5x-4(3x+28)=-10
y=3x+28
-5x-12x-112=-10
y=3x+28
-17x=-10+112
y=3x+28
-17x=102
y=3x+28
x=102/(-17)
y=3x+28
x=-6
y=3*(-6)+28
x=-6
y=-24+28
x=-6
y=4
x=-6
(x,y)=(-6,4)
Step-by-step explanation:
5x+23=0
