Answer:
infinite
Step-by-step explanation:
1/6 of 12 is 2
1/6 of 18 is 3
Plug them in
2z-3=2z-3
meaning you can put literally any number in place of z and it'd work.

24 inches.
Step-by-step explanation:
Answer:
8.4in²
Step-by-step explanation:
We are given the dimensions of a box as :
7in = Height
6in = Length
2in = Width
The volume of a box = Length × Width × Height
Volume of a box = 7in × 6in × 2in
= 84in²
We are also told in the question to find the volume of the box if it is scaled down by a factor of 1/10
Hence,the new volume = 84in² × 1/10
= 8.4in²
Therefore, the volume of the box if it is scaled down by a factor of 1/10 is 8.4in²
The formula for the area of a trapezium is as follows:
<span>area=<span>12</span>(a+b)h
</span>
Let a be the shorter base. Then a = h + 3.
Let b be the longer base. Then b = h + 7.
Substituting these values for a and b in the general formula gives:
<span>
area = 225 = <span>12</span>(h+3+h+7)h = <span>h^2</span>+5h</span>
So you need to solve the following quadratic:
<span><span>h^2</span>+5h−225=0</span>
Step 1: Use quadratic formula with a=1, b=5, c=-225.

Answer:
did that first one its false
A= 53, B= 100, C= 27 (the last option)
BC is the longest side because it is opposite the largest angle ( not true)
