Answer:
3(4x + 1)(x - 4) Answer choice B
Step-by-step explanation:
-12x^2 + 45 + 12
You would take out the -3 in the equation.
-3(4x^2 -15x - 4)
You can then multiply the first 4 and the last -4 and get a -16. You can then find two numbers that would multiply to -16 and add to -15.
You would do this by listing the factors of -16, which the numbers 1 and -16 would work.
You would then substitute each value in for the 17x and add them together, which this is just separating the value 17x.
3(4x^2 - 16x + x - 4)
3(4x^2 - 16x)(x - 4)
You can then take ou ta four for the first function in the parentheses.
3(4x(x - 4) 1(x - 4))
Then you take the function from the outside and the inside.
3(4x + 1)(x - 4)
The answer to the question would be B.
If you subtract 2 from 9 you'll get 7. Add 7 to three and you'll get y=10 when x=3.
Part
A:
<span>In
the expression given, 65 + 15w + 25m: 65 =
constant; 15 and 25 = coefficients; w and m = variables.</span>
Thus,
to define:
Constant
is a number which the value is already fixed.
Variable
is the unknown value in the algebraic expression.
Coefficient
is a number which is placed before a variable that indicates how many times the
variable is to be multiplied.
65 + 15w + 25m
65 = 15 (1) + 25 (2)
Part
B:
Let
x be the savings account balance
W
= # of weeks
M
= frequency of mowing the lawn
First,
let’s use the expression given above: 15w + 25m.
Since we are solving for a
constant, only the variables and coefficient of the expression given are to be
used.
Then,
we substitute the variables’ corresponding values.
X
= 15 (20) + 25 (3)
Therefore,
the savings deposits will amount to:
X
= 300 + 75
X
= $375
Part
C:
$75
+ w + 3m
Constant
will be $75.
Variables:
w = no weekly deposit, m = 3
Coefficients:
w = 1, m = remains at 25
This is because we need to adjust the variables and coefficients to solve for the constant.
Answer:
50 square meter/hour
Step-by-step explanation:
using unitary method-
if 36mins(3/5 of 60mins)= 30 square meter
1min=30/36
60mins=(30/36)*60
in 60mins=50square meter or 50 square meter/hour
Answer:
The answer is
<h2>
</h2>
Step-by-step explanation:
The distance between two points can be found by using the formula
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(4,-9) and (-6,-10)
The distance between them is
We have the final answer as
