Answer: 46
Step-by-step explanation:
You can simplify this using PEMDAS:
Parentheses
Exponents
Multiplication/division
Addition/subtraction
Move through the steps in that order.
In this case, the first two steps are absent, so multiply first:
20 - 16 + 42
Then, add and subtract:
46.
Answer:
B
Step-by-step explanation:
We want to find the equation of a line with a slope of 3 that includes the point (0, 5).
We can use the slope-intercept form, given by:

Where m is the slope and b is the y-intercept.
Notice that the given point (0, 5) is already the y-intercept. So, b = 5.
By substitution, we acquire:

Hence, our answer is B.
Answer:
Step-by-step explanation:
2x² -x - 6 = 2x² - 4x + 3x - 3*2
= 2x*(x - 2) + 3*(x - 2)
= (x-2)(2x + 3)
A = 2x² -x - 6
A = (x - 2)(2x + 3)
length*width = (x - 2)(2x + 3)
length * (2x +3) = (x - 2)(2x + 3)

length = x - 2
Answer:
Yes
Step-by-step explanation:
X2+10x+25=0
So let's solve
10=5,5
25=5,5
So let's continue
X2+5x+5x+25
Let's factorise
X(x+5)+5(x+5)=0
(X+5)(x+5)=0
So
X+5=0
Substrate 5 from both sides
X=-5(twice)
So the answer is yes
