Answer:
10v² - 27v - 17vx - 20x²
Step-by-step explanation:
Given
(5v + 4x)(2v - 5x - 3)
Each term in the second parenthesis is multiplied by each term in the first parenthesis, that is
5v(2v - 5x - 3) + 4x(2v - 5x - 3) ← distribute both parenthesis
= 10v² - 25vx - 15v + 8vx - 20x² - 12x ← collect like terms
= 10v² - 15v - 17vx - 12x - 20x²
That would be B
|-6| + |4| = 6 + 4 = 10
To answer this question, we must know some identities:
1. cos(x) is an even function, so cos(x)=cos(-x) [this makes choice (c) true]
2. sin(x) and cos(x) are the same periodic functions with a phase-shift of pi/2, so that sin(x+pi/2)=cos(x) [this makes choice (b) true]
3. also, sin(x) is symmetrical about pi/2, and cos(x) is symmetrical about x=0. This means that sin(x)=cos(pi/2-x) [ this case is not present in the choices ]
Answer: What did Jason practice making
Step-by-step explanation: Explain what Jason was making
Note the equal sign. What you do to one side, you do to the other.
Isolate the variable. Divide 4 from both sides
(-52)/4 = (4m)/4
m = -52/4
m = -13
-13 is your answer for m
hope this helps
