First off, AY GET OFF OF YOUTUBE BOI XD
Second off, since the area of the triangle is 21 square feet, you do 21/6, which equals 3.5.
So you need to find (2x-1)= 3.5.
So the answer is 2.25.
Answer:
1216
Step-by-step explanation:
Plug in 8 everywhere you see x.
8[(7*8)+(12*8)]
Solve, using order of operations (PEMDAS).
8(56+96)
8(152)
1216
The answer is 20°C if you live in a very cold place so yah
X^4 - 3x^2 + 2
= (x^2 - 1)(x^2 - 2)
Note that x^-1 is the difference of 2 squares:-
= (x + 1)(x - 1)(x^2 - 2) Answer
Let the number of Matinee tickets be x
Let the number of evening tickets be y
Number of sold tickets = 63, this means that: x+y = 63 ......> equation I
Price of matinee ticket = 10 and price of evening tickets = 14
Total money collected = 742, this means that 10x + 14y = 742 .....> equation II
From equation I: x = 63 - y .........> equation III
Substitute by equation III in equation II:
10(63-y) + 14y = 742
630 - 10y + 14y = 742
4y = 742 - 630 = 112
y = 112/4 = 28
Substitute by the value of y is equation III:
x = 63-28 = 35
Based on the above calculations:
number of matinee tickets = x = 35 tickets
number of evening tickets = y = 28 tickets
