Answer:(a=5,b=3)
7a-3b = 26--------(1)
a + 2b =11---------(2)
on mutlplying by7 in eq 2
= 7a+14b=77-------(3)
from eq(1) and (3) (on substracting)
7a+14b=77
7a-3b=26
________
=-17b=51
b=51/17
b=3
on putting value of b in eq 1
7a-3b = 26
=7a-9=26
7a=35
a=5

Linear decreasing
The answer would be ΔKML because the right angle of ΔKML is in the same place as <span>ΔJKL</span>
I believe the answer is 5040
Answer:
Option C or 56.25×πcm^2
Step-by-step explanation:
The formula to find the circumference of a circle is P=2×π×r.
The formula to find the area of a circle is A=π×r^2.
Step 1: Find the radius by expanding your circumference answer to get the entire formula. In this case 15π=2×π×7.5 Look familiar? You have found the radius!
Step 2: Put the radius in the formula to find the area. Since this answer is not looking for a specific number that's all you have to do. In this case, A=π×7.5^2. Or A=π×56.25.
Step 3: You have the answer. Hope this helps
