Answer:
8 in, 8 in and 20 in
Step-by-step explanation:
Let the equal sides of the isosceles triangle be x, then
The base = 2.5x
Sum the 3 sides and equate to the perimeter of 36
x + x + 2.5x = 36
4.5x = 36 ( divide both sides by 4.5 )
x = 8
Thus the 2 equal legs = 8 in
base = 2.5x = 2.5 × 8 = 20 in
The first four terms of the sequence that follows the rule is 2, -1, 5 and -7
<h3>What is an
equation? </h3>
An equation is an expression that shows the relationship between two or more numbers and variables. An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.
A sequence of numbers follows the rule: multiply the previous number by -2 and add 3. Let a represent the third term, hence if the 4th term is -7:
-7 = -2a + 3
a = 5
Let b represent the second term, hence:
5 = -2b + 3
b = -1
Let c represent the first term, hence:
-1 = -2c + 3
c = 2
The first four terms of the sequence that follows the rule is 2, -1, 5 and -7

Answer:
18
Step-by-step explanation: 24/4=6 so if you multiply one by six you must multiply the other by six to make sure they're to the same scale 3*6=18
