So, the coefficients are 24, -3, and 7. The letters next to the coefficients are called "variables".
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
In the number 23,876 the 2 has a value of 20,000. In the number 3,254 the 2 has a value of 200.
Therefore, the 2 in 23,876 is 100 times greater than the 2 in 3,254.
Hope this helps:)
Hello from MrBillDoesMath!
Answer:
x = 50
Discussion:
(4x +5) ( 2x - 2) = 8x^2 - 8x + 10x - 10
= 8x^2 + 2x - 10 (A)
(16x^8)/(2x^6) + 90 = 8x^2 + 90 (B)
Setting (A) = (B) gives
8x^2 + 2x - 10 = 8x^2 + 90
Subtract 8x^2 from both sides:
2x - 10 = 90
Add 10 to both sides:
2x = 90 + 10 = 100
Divide both sides by 2:
x = 100/2 = 50
Thank you,
MrB
