Answer: 76.2
Step-by-step explanation:
Perimetar of isiscales triangle is calculated using equation;
P=b+2a
b=9
P=49
lets find sides of triangle.
P-b=2a
a=(P-b)/2
a=49-9/2
a=40/2=20
If another triangle is similar that means that his base and sides are proportional to first triangle.
Base of first trianlge b₁=9
Base of similar triangle is b₂=14
use proportion to find out side of similar triangle:
b₁:b₂=9:14
a₁:a₂=9:14
a₁=20
20: a₂=9:14
a₂=14*20/9=280/9=31.1
Perimetar of second triangle is:
P₂=b₂+2a₂
P₂=14+2*31.1=14+62.2=76.2
Since m= slope =2, slope is rise/run, or (y2-y1)/(x2-x1), we'll make the point (6,6) = (x1,y1)
In point-slope form, y-y1 = m (x-x1) -->
y-6 = 2 (x-6)
y-6 = 2x-12
+6 = +6
y = 2x-6
-2x = -2x
-2x+y = -6
Answer:
x=8

Answer:
(15-3)x4+9=57
Step-by-step explanation:
15-3=12
12x4=48
48+9=57
57=57
6,440 divided by 28 is 230.....
