Answer:
x = 1
Step-by-step explanation:
3^(4x + 2) = 9^(x + 2)
Make 9 with base 3.
3^(4x + 2) = (3^2)^(x + 2)
3^(4x + 2) = 3^(2x + 4)
Cancel bases.
4x + 2 = 2x + 4
Subtract 2 and 2x on both sides.
4x - 2x = 4 - 2
2x = 2
Divide 2 on both sides.
x = 1
Answer:
C.
Step-by-step explanation:
The next step is to add (1/2 * 8)^2 = 4^2 = 16 to the 8x and subtract 16 from the + 6:
- to give (x^2 + 8x + 16) + 6 - 16 as the next step in the process.
The extreme minimum is +6 - 16 = -10.
Answer:
x=90
Step-by-step explanation:
So, since x-20 is the vertical angle directly near 70, we can say:
x-20=70.
if we solve x is 90.

Answer:
-4/8
Step-by-step explanation:
slope=rise/run
y2-y1/x2-x1
(-2,3) (6, -1)
x1 y1)( x2 y2
-1 - 3= (-4)
6-(-2)
6+2=8
m/slope= -4/8
Answer:
V = 60 m3
Step-by-step explanation:
Volume of a square pyramid:
V = (1/3)a2h
Slant Height of a square pyramid:
By the pythagorean theorem we know that
s2 = r2 + h2
since r = a/2
s2 = (1/4)a2 + h2, and
s = √(h2 + (1/4)a2)
This is also the height of a triangle side
