Answer:
x ≈ 46°
Step-by-step explanation:
Since the triangle is right use the sine ratio to solve for x
sinx =
=
, hence
x =
(
) ≈ 46°
Answer:
B. 14x^3+39x^2+18x+20
Step-by-step explanation:
Given polynomials are:
![(7x^2+2x+4)(2x+5)\\For\ product\\(2x+5)(7x^2+2x+4)\\= 2x(7x^2+2x+4)+5(7x^2+2x+4)\\= 14x^3+4x^2+8x+35x^2+10x+20\\Combining\ alike\ terms\\= 14x^3+4x^2+35x^2+8x+10x+20\\=14x^3+39x^2+18x+20](https://tex.z-dn.net/?f=%287x%5E2%2B2x%2B4%29%282x%2B5%29%5C%5CFor%5C%20product%5C%5C%282x%2B5%29%287x%5E2%2B2x%2B4%29%5C%5C%3D%202x%287x%5E2%2B2x%2B4%29%2B5%287x%5E2%2B2x%2B4%29%5C%5C%3D%2014x%5E3%2B4x%5E2%2B8x%2B35x%5E2%2B10x%2B20%5C%5CCombining%5C%20alike%5C%20terms%5C%5C%3D%2014x%5E3%2B4x%5E2%2B35x%5E2%2B8x%2B10x%2B20%5C%5C%3D14x%5E3%2B39x%5E2%2B18x%2B20)
The product of given polynomials is:
14x^3+39x^2+18x+20
Hence, Option B is correct ..
Answer:
D. 5x^2 + 2y^2 + 12x + 5y
Step-by-step explanation:
6x + 2y + y^2 + 6x + 2y + y^2 + 4x^2 + x^2 + y
6x + 6x = 12x
12x + 2y + y^2 + 2y + y^2 + 4x^2 + x^2 + y
2y + 2y + y = 5y
12x + 5y + y^2 + y^2 + 4x^2 + x^2
y^2 + y^2 = 2y^2
2y^2 + 4x^2 + x^2 + 12x + 5y
4x^2 + x^2 = 5x^2
2y^2 + 5x^2 + 12x + 5y
5x^2 + 2y^2 + 12x + 5y
Answer:
the eq of line y= x+7 for sure
Answer:
The expressions here are;
6 + 5w
3-16v
4v+ 1
7-v
Step-by-step explanation:
Here, out of the given set, we want to choose all options that are expression.
To do this, we should understand that expressions do not have the equality sign like equations
So expressions are those in the set in which we do not have an equality sign
The right answer is thus;
6 + 5w
3-16v
4v + 1
7-v
