An acute angle is any angle that is less than 45 degrees. So, for example if both angles were 89 degrees, then their sum would be greater than 90 degrees.
Answer:
C
Step-by-step explanation:
Expand the factors and compare the coefficients of like terms.
Given
(mx + 2)(3x - 5) ← expand using FOIL
= 3mx² - 5mx + 6x - 10
Compare to 12x² - 14x - 10
For the 2 to be equal, then the coefficients of like terms must be equal.
Compare coefficients of x² terms
3m = 12 ( divide both sides by 3 )
m = 4 → C
1. Put all X on the left hand side.
2. Move all numbers to the right hand side
3. Simplify both sides.
X=15-18+9+3
=9
Answer:
D. Subtract 4 from both sides
Explanation:
I just learned about quadratic equations in school. The first step of solving quadratic equations is to make sure it is in standard form and equal to 0.
Standard form:
ax^2 + bx + c = 0
Answer:
see below
Step-by-step explanation:
The following definitions apply:
if p, then q . . . . conditional statement
if q, then p . . . . converse
if ~p then ~q . . . inverse
if ~q then ~p . . . contrapositive
You have ...
p = "it is October 31"
q = "it is Halloween"
(a) The <em>converse</em> is ...
If it is Halloween, then it is October 31.
(b) The <em>inverse</em> is ...
If it is not October 31, then it is not Halloween.
(c) The <em>contrapositive</em> is ...
if it is not Halloween, then it is not October 31.
