Answer:
465 in²
Step-by-step explanation:
square area: A = lw
triangle area: A = 
lw (or base x height)
= (15)(15) = 225
= (8)(15) = 60
There is one square and 4 triangles so...
225 + 4(60) = 465 in²
Answer:
5
Step-by-step explanation:
=>
; [∵ 25÷5=5]
=>1*5
=>5
There aer infinite numbers
to make it easier we can solve for y
2x-8y=-4
x-4y=-2
-4y=-x-2
y=(1/4)x+(1/2)
some values aer
x=0, y=1/2
x=-2, y=0
etc
Answer:
21 and 30
Step-by-step explanation:
x + y = 51
x - y = 9
add the two equations and y's will cancel out
2x = 42 divide by 2
x = 21 so put 21 in for x in the top equation and solve
21 + y = 51
y = 30
