40×4×4=640
b=20 h=4
using formula:
1/2×base×height
1/2×20×4=40
its says scale by factor 4:
b=80 h=16
using formula:
1/2×base×height
1/2×80×16=640
answer------>>>>640cm^2
Answer:
x = 50
Step-by-step explanation:
SU is a midline segment and is one half the measure of VW, thus
VW = 2SU , that is
x - 46 = 2(x - 48) ← distribute
x - 46 = 2x - 96 ( subtract x from both sides )
- 46 = x - 96 ( add 96 to both sides )
50 = x
The rule is adding 5 if we say n is 2 then nth term is
n + 5(or so I hope )
Answer:
y-8=-4/3(x+2)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-4-8)/(7-(-2))
m=-12/(7+2)
m=-12/9
simplify
m=-4/3
y-y1=m(x-x1)
y-8=-4/3(x-(-2))
y-8=-4/3(x+2)
