Complete the following: (2x +3y)^2 = (2x)^2+2(2x)(3y) +(____)^2

FrozenT [24]

Answer:

Complete function will be $(2x+3y)^2=(2x)^2+(3y)^2+2\times (2x)\times (3y)$

Step-by-step explanation:

We have given equation $(2x+3y)^2=(2x)^2+2\times (2x)\times (3y)+..........^2$

We have to find the function in place of blank space and complete the function

We know the algebraic equation $(a+b)^2=a^2+b^2+2ab$

So $(2x+3y)^2=(2x)^2+(3y)^2+2\times (2x)\times (3y)$

So in place of blank pace there will be $(3y)^2$

And complete function will be $(2x+3y)^2=(2x)^2+(3y)^2+2\times (2x)\times (3y)$

A number is increased by 50% and then another 25%. By how much is it increased in total?

blsea [12.9K]

Answer:

87.5 percent

Step-by-step explanation:

when you have to increase a number by 50 percent you are multiplying it by 1.5

later when you increase the number by 25 percent you multiply it by 1.25

you can multiply 1.5 by 1.25 to get your answer

1.5 * 1.25 is 1.875

so the percent increase is 87.5 percent
