Step-by-step explanation:
Answer:
-3
Step-by-step explanation:
-14-6x=x+7
-14-6x+14=x+7+14
-6x=x+21
-6x-x=x+21-x
-7x=21
\frac{-7x}{-7}=\frac{21}{-7}
x=-3
(2x+1)+89=180. 180 is the angle of a straight line. Set your two known sides equal to 180 and solve for x if needed.
Answer:
His gain percent would have been 8%
Step-by-step explanation:
The key to answering this question is to first calculate the price at which the wheat flour was bought.
Mathematically;
% profit = (selling price-cost price)/cost price * 100%
Let the cost price be $x
Thus;
% profit = (30-x)/x * 100
20 = 100(30-x)/x
20x = 3000-100x
100x + 20x = 3000
120x = 3000
x = 3000/120
x = Rs 25
So let’s assume he sold at Rs 27
His profit would have been 27-25 = 2
His gain or loss percentage would’ve been;
2/25 * 100/1 = 200/25 = 8% (gain, since selling price is greater than the cost price)
The polynomial will be given as P(x) = a(x + 3)² (x – 2)³. Then the correct option is D.
A polynomial expression is an algebraic expression with variables and coefficients. Unknown variables are what they're termed. We can use addition, subtraction, and other mathematical operations. However, a variable is not divisible.
5th degree polynomial has a zero at x= -3 with multiplicity of 2 and a zero of x=2 with multiplicity of 3 and value of the function is neg. when x = -4.
Then the factor of the polynomial will be (x + 3) and (x – 2).
Then the polynomial will be given as,
P(x) = a(x + 3)² (x – 2)³
Where a is the leading coefficient.
Then the correct option is D.

What is the area
The area of the rectangle is found by multiplying the length and the width together, giving the polynomial 21x^4 + 56x^3 + 49x^2.
The area of a rectangle can be found by multiplying the length by the height. In this case, the height of the rectangle is 7x^2 and the width of the rectangle is 3x^2 + 8x + 7
So, we multiply these two expressions together to get the area:
Area = 7x^2 * (3x^2 + 8x + 7) = 21x^4 + 56x^3 + 49x^2.
This is a polynomial and it is in standard form, as the terms are ordered from highest degree to lowest degree.
