Answer:
Answer choice b) 2x^4+11x^3+12x^2−10x−8
Step-by-step explanation:
(x^2+4x+2)(2x^2+3x+−4)
=(x^2)(2x^2)+(x^2)(3x)+(x^2)(−4)+(4x)(2x^2)+(4x)(3x)+(4x)(−4)+(2)(2x^2)+(2)(3x)+(2)(−4)
=2x^4+3x^3−4x^2+8x^3+12x^2−16x+4x^2+6x−8
2x^4+11x^3+12x^2−10x−8
Witch leave us with the answer choice B) 2x^4+11x^3+12x^2−10x−8
Answer
40
The formula to determine the area of the right triangle is a*b/2
First, let’s input the numbers into the formula.
16*5/2
Now we need to solve.
16*5= 80
80/2= 40
Therefore, the answer would be 40.
So, for this kind of problem you need to FOIL.
This stands for:
F- first
O-outer
I-inner
L-last
What this means is that:
step 1- multiply the FIRST terms in each thing. So for example in problem 6 of the problems you sent it would be x times x. =
step 2- multiply the OUTER terms in each thing. So for example in problem 6, it would be x times 3. =3x
step 3- multiply the INNER terms in each thing. So for example in problem 6, it would be 6 times x. =6x
step 4- multiply the LAST terms in each thing. So for example in problem 6, it would be 6 times 3. =18
step 5: you add all of your products. So for problem 6 it would be y=
+ 9x +18.
The answer is 45%
1. Calculate how many ml of blue pigment are in 4ml of ink A if it contains <span>10% blue pigment:
4 ml is 100%
a ml = 10%
4 ml : 100% = a : 10%
a = 4 ml * 10% : 100% = 0.4 ml
2.</span> Calculate how many ml of blue pigment are in 10ml of ink A if it contains x% blue pigment:
10 ml is 100%
b ml = x%
10 ml : 100% = b : x%
b = 10 ml * x% : 100% = x/10 ml
3. 2. Calculate how many ml of blue pigment are in 14ml (because Four milliliters of ink A is added to 10 milliliters of ink B) of total mixture if it contains 35% blue pigment:
14 ml is 100%
t ml = 35%
14 ml : 100% = t : 35%
t = 14 ml * 35% : 100% = 4.9 ml
4. <span>What percentage of blue pigment is in the mixture of the two inks:
a + b = t
0.4 + x/10 = 4.9
x/10 = 4.9 - 0.4
x/10 = 4.5
x = 4.5 * 10 = 45</span>
