<span>The expressions that cannot be factored using integral coefficients and integral constants is the below:
</span>b. 2x2 + x + 4
d. x2 - 2x - 4
For a. 25x2 - 40x + 16 the factors are (5x – 4) (5x – 4)
For c. 6x2 - 2x - 20 the factors are (2x - 4) (3x + 5)
Answer:
-7
Step-by-step explanation:
let the first term be a
thus, a=56
common difference d= U2-U1 = 49-56= -7
I believe it’s 4 since he’s in dept with 4 dollars so that’ll be -4, but the absolute value is 4 since it’s 4 spaces away from 0.
Answer:
Step-by-step explanation:
sin(x)=cos(x) × tan(x)
=(-2√23)×(√24)
=(-2√23)×(2√6)
=(-4√138)
=(-4(2√(3×23)))
=(-8√69)
Answer:
<h2>- 2</h2>
Step-by-step explanation:
The slope intercept form of an equation of a line:
m - slope
b - y-intercept
We have the equation of a line in the standard form
Convert to the slope-intercept form:
<em>subtract 4x from both sides</em>
<em>divide both sides by 2</em>
Therefore the slope is equal to -2.
Other method:
If we have the equation of a line in standard form Ax + By = C
or in general form Ax + By + C = 0, then the formula of a slope is
We have A = 4 and B = 2. Substitute:
