X+4=y=-2x-2
x+4=-2x-2
add 2x to both side
3x+4=-2
minus 4 both sides
3x=-6
divide 3
x=-2
sub back
y=x+4
y=-2+4
y=2
(x,y)
(-2,2)
Answer: 11.4 m
Step-by-step explanation:
The scenario depicted is that of a right angled triangle with the 7 meters being the base and the 9 meters being the height.
The length of the ladder will therefore be the Hypothenuse.
Using the Pythagorean Rule:
a² + b² = c²
with c being the hypothenuse
7² + 9² = c²
49 + 81 = c²
c²= 130
c = √130
c = 11.4 m
Ratio of perimeters of smaller solid to larger solid = ratio of the sides of the corresponding sides of smaller solid and larger solid .
Let the perimeter of smaller solid =x and perimeter of larger solid =y. Therefore
Therefore the answer is 13/17 .
