Answer:
b
Step-by-step explanation:
Answer:
yes
Step-by-step explanation:
Given the 2 equations
y = 
x + 6 → (1)
y = - x + 5 → (2)
Substitute y = x + 6 into (2)
x + 6 = - x + 5 ( add to both sides )
x + 6 = 5 ( subtract 6 from both sides )
x = - 1 ( divide both sides by )
x = 
= - 
← one solution
Answer:
40,44,48,52
Step-by-step explanation:
These are multiples of 4 because 4 can be multiplied into all of them like
4x11=44
4x10=40
4x12=48
4x13=52
So we got a rectangle base, 2 rectangle sides and 2 triangle sidess
ok so 6cm=height total
ok
so the trianglular sides
the base is4 and height is 6
2 triangles so
2 times 1/2 times 4 time 6=24 for both triangles
now the rectangle parts
the bottom bit is 4 by 12 or 48
the back one is 7 by 12 or 84
the front one is unknown because we don't know the side length of the front side (if we use pythagoran theorem and stuff we get that the side is √(65-8√13)) or about6.01, so I would say about 6)
so 6 times 12=72
total is
triangles+rectangles=
24+48+84+72=
228
about 228 square cm (if that front side length is 6)
