If the sol'ns are -9 and 9, then we can use this to form our eq'n:
(x - 9)(x + 9) = 0
x^2 - 81 = 0
so...
x^2 + z - 103 = x^2 -81
z - 103 = -81
z = -81 + 103
z = 22
Answer:
Step-by-step explanation:
7 x 7 = 49 which is the area of the square
7 x 12 x .5 = 42 so if you add them together
49 + 42 = 91
Answer-
The coin has 5 angles and 5 sides
Hi there!
Use PEMDAS:
Evaluate inside of parenthesis:
(264 + 3 × 7)
Multiply:
(264 + 21)
Add:
285
Divide by 3:
285 ÷ 3 = 95
This is the concept algebra.
Volume of of paint that is required to paint large shipping crate is a liters.
suppose the volume of this crate is x cubic units.
The volume of the next crate to be painted will be 2x cubic units.
Hence the amount of paint required to paint the crate will be:
(volume of bigger crate)/(volume of smaller crate)×(volume of liters required to paint the first crate)
=(2x)/(x)×a
=2a liters
To paint the new crate 2a liters of oil is needed.
