Use distributie property which is
a(b+c)=ab+ac
therefor
6x(x-4)=6x^2-24x
distribute the negative 1 infroont of the (9x-1)
-1(9x-1)=-9x+1
now we have
6x^2-24x-16x^2-9x+1
gropu like terms
6x^2-16x^2-24x-9x+1
add like terms
-10x^2-33x+1 is simplest form
And what else you can not solve that problem
Answer:
Multiplying the variables and numbers in the parentheses by the number next to them.
Step-by-step explanation:
Answer:
obtuse
Step-by-step explanation:
The largest angle is more than 90°, so the triangle is called an "obtuse" triangle.
Here are the classifications based on the measure of the largest angle:
< 90° -- acute triangle
= 90° -- right triangle
> 90° -- obtuse triangle . . . . . like the one in this problem statement
Step-by-step explanation:
So when a question asks what is x% of the y number. It's asking you to convert the x into decimal form by dividing by 100 and then multiply it by y. This gives you the equation: 
which gives you x% of y. so 15% of 43 is 
. 43% of 300 is 
.
the 12% of what number is 43 is a bit more tricky. It's asking you to instead find a number in which 12% of it is equal to 43. So instead of plugging solving for the percentage (which is already given) you solve for y. This gives you the following equation: 
. Now all you do is calculate 12/100 which gives you 
. now divide both sides by 0.12 to solve for y. This gives you 
43 is what percent of 106? This question is also a bit tricky, but instead of solving for y, you're solving for x. So plug in the known values, which gives you the equation: 
. Divide both sides by 106 to get 
and now multiply both sides by 100. this gives you 
which is the answer 40.57%
What percent of 43 is 6. This is asking the same thing just in a different way. So percentage = unknown, entire number = 43, entire number * percentage = 6. With these values we get the equation: 
. Divide both sides by 43 to get 
now multiply by 100 to get 
which is the answer 13.95%
