Answer:
5/8
Step-by-step explanation:
28x + 4 can be factorised because 28 is a multiple of 4
so it can become
4(7x+1)
35x + 5 can be also factorised because 35 is a multiple of 5
5(7x+1)
we can now rewrite the expression as
6/4(7x+1) * 5(7x+1)/12
we can “eliminate” the two 7x+1 and simplify 6 with 12
so it remains
1/4 * 5/2 = 5/8
Answer:
Option C. 2x + 20 / x² + 6x – 40
Step-by-step explanation:
f(x) = x + 16 / x² + 6x – 40
g(x) = 1 / x + 10
To find f(x) + g(x), please refer to the attached photo.
Questions is incomplete however from what i understand it is asking (4^2)^4 which can be made that the arguement of the function is correct because its is the multiplication of radicals which however way you put it will equal the same
Hello from MrBillDoesMath!
Answer:
72
Discussion:
Total Surface area = area of pyramid base + 4 ( area of triangular face)
In our case this becomes
4*4 + 4( (1/2) (4)(7) ) =
= 16 + (2)(4)(7)
= 16 + 56
= 72
which is the first choice.
Note: the area of a triangular face was computed using (1/2) b h, which in our case is
(1/2) (4) (7)
Thank you,

Answer:
Equations in slope-intercept form for three different lines that intersect at (–2, 3) are y=-x+1 , y=3 and y=x+5
Step-by-step explanation:
General equation of slope intercept form :
We are supposed to find equations in slope-intercept form for three different lines that intersect at (–2, 3).
Substitute the value in the general equation
y-3=m(x+2)
Now substitute any 3 values of m
At m = -1
At m =0
At m =1
They all intersect at the given point.
So, equations in slope-intercept form for three different lines that intersect at (–2, 3) are y=-x+1 , y=3 and y=x+5
