A negative sign and a negative sign next to each other is a positive sign ex..
-14 - -3
= -14 + 3
= -11
a negative sign and a positive sign next to each other is a positive sign ex..
-14 + -3
= -14 - 3
= -17
the bigger a negative number the smaller it is
the bigger a positive number the larger it is
which supports the rule if you are subtracting the
number will become smaller and if you are adding
the number will become larger
Answer:
<h2><u><em>
n = 4</em></u></h2>
Step-by-step explanation:
3n + 16 = 7n
3n - 7n = -16
-4n = -16
n = -16 : (-4)
n = 4
---------------- check
3 * 4 + 16 = 7 * 4
12 + 16 = 28
28 = 28
the answer is good
The formula for area of a triangle is A = bh/2, where b is the base length and h is the height of the triangle. For this triangle, the base is twice as big as the height; the base and height are represented as follows.
Height: h
Base: 2h
The area of the triangle is 64. Plug all values and expressions accordingly into the formula for area and solve algebraically for h.
A = bh/2
64 = 2h(h)/2
64 = 2h²/2
64 = h²
8 = h
b = 2h
b = 2(8)
b = 16
Answer:
The height of the triangle is 8 units and the base is 16 units.
