Answer:
Step-by-step explanation:
Given system of equations:
To solve by the method of substitution, substitute the first equation into the second equation and rearrange so that the equation equals zero:
Factor the quadratic:
Apply the <u>zero-product property</u> and solve for x:
Substitute the found values of x into the <u>second equation</u> and solve for y:
Therefore, the solutions are:
9cm
Imagine there are 2 triangles solve for one 3*3=9\2=4.5
Then add
4.5+4.5=9
Question: Simplify: (3x^3)^2
Step by Step:
STEP 1 : Equation at the end of step 1
(3x³)²
STEP2:
2.1 x³ raised to the 2 nd power = x( 3 * 2 ) = x⁶
Answer: 3²x⁶
Hope it Helps.
Multiply it out and collect terms.
y = (x - 3)² + 36
y = (x² -6x +9) +36
y = x² -6x +45
