Corresponding sides have the same ratio, so
x/15 = 12/(12+8) = 3/5
x = 15*3/5
x = 9
Answer:
615.44 m²
Step-by-step explanation:
the area of circle = 3.14 x 14² = 3.14×196
= 615.44 m²

y - y₁ = m(x - x₁)
y - (-10) = -1⁴/₂₁(x - 6)
y + 10 = -1⁴/₂₁(x) + 1⁴/₂₁(6)
y + 10 = -1⁴/₂₁x + 7¹/₇
- 10 - 10
y = -1⁴/₂₁x - 3¹/₇
Answer:
x and y are the variables
( − 5 ) ( + 5 ) ( 2 + 2 5 )
