Answer: H = 3
Step-by-step explanation:
h=2(A
/a+b) A= area, a= one of the bases, b= other base
2(18/5+7)
Step-by-step explanation:
AB=BC
8x+6=6x+18
2x=12
x=6
so
AB= 48+6=54cm
BC=36+18=54cm
AD=CD
8y+20=12y-8
-4y=-28
y=7
so
AD= 84-8=76cm
CD=56+20=76cm
AE=2x+4y
AE=2×6+4×7
AE=40cm
AC=2×40=80cm
Multiply 532 and 4 then divide by 152 and it should be 14.
Answer:
No
Step-by-step explanation:
She needs at least another 2 coordinate pairs to test if her evaluation is correct. For instance, the next pair could be (7,22). Then, the pattern wouldn't be increasing by 4. It would not have a constant of proportionality.
