Answer:
2x-10
Step-by-step explanation:
Using distributive property:
2 times x = 2x
2 times -5 = -10
X^2-y^3=6
x^2-6=y^3
y= (x^2-6)^1 by 3
Answer:
the areas of these triangles are 83.2cm² and 46.8cm²
Step-by-step explanation:
1. If the triangles are similar and the ratio of the perimeter ois 4:3, then the areas are in the following ratio:
4²:3²
16:9
2. The sum of their areas is 65 cm², then, you can calculate the area of the larger triangle as following:
130(16/16+9)
130(0.64)
=83.2cm²
3. The area of the smaller triangle is:
130(9/16+9)
130(0.36)
46.8cm²
