if ABC is a isosceles triangle with sides(2a+b)cm, (6a+2b+1)cm and a base of 4a cm, if it's perimeter is 28 find sides

Katyanochek1 [597]

Answer:

a=1.5, b= 3

Step-by-step explanation:

sum of all sides will give us perimeter. Therefore

2a+b+6a+2b+1+4a=28

12a+3b+1=28

12a+3b=27....eqn1

since t two sides of this isosceles triangle are equal:

2a+b=4a

2a=b

$a=\frac{b}{2}$

substituting $\frac{b}{2}$ $.$ in the first equation whenever we encounter a we will have:

$12(\frac{b}{2})+3b=27\\$

6b+3b=27

9b=27

b=3

therefore $a= \frac{b}{2} =\frac{3}{2} =1\frac{1}{2} or 1.5$

The function f(x)= 3(1.4)' gives the length (in inches) of an image after being enlarged by 10% x times.

kondaur [170]

Answer:

3.99 inches

Step-by-step explanation:

The correct question is

The function f(x) = 3(1.1)^x gives the length (in inches) of an image after being enlarged by 10% x times.

What is the length of the image after it has been enlarged 3 times? Round your answer to the nearest hundredth

we have

$f(x)=3(1.1)^x$

This is a exponential growth function

where

f(x) represent the length (in inches) of an image

x is the number of times the image is enlarged

For x=3

substitute in the exponential equation

$f(x)=3(1.1)^3=3.99\ in$

Find the TWO integers whos product is -12 and whose sum is 1

ahrayia [7]

Answer:

$\rm Numbers = 4 \ and \ -3.$

Step-by-step explanation:

Given :-

The sum of two numbers is 1 .

The product of the nos . is 12 .

And we need to find out the numbers. So let us take ,

First number be x

Second number be 1-x .

According to first condition :-

$\rm\implies 1st \ number * 2nd \ number= -12\\\\\rm\implies x(1-x)=-12\\\\\rm\implies x - x^2=-12\\\\\rm\implies x^2-x-12=0\\\\\rm\implies x^2-4x+3x-12=0\\\\\rm\implies x(x-4)+3(x-4)=0\\\\\rm\implies (x-4)(x+3)=0\\\\\rm\implies\boxed{\red{\rm x = 4 , -3 }}$

Hence the numbers are 4 and -3
