[I think you wrote the question wrong] -5 multiplied by -4 equals 20 and -5 and -4 equals -9
Answer: 1/3 (p+45)
Step-by-step explanation:
when you multiply p by 1/3, a fraction, it kinda divides. the parentheses come first so that’s p+45=45p. 45px1/3 (or divided by three), is 15p

Answer:
X would be equal to 5.
Step-by-step explanation:
20 divided by 16 equals 1.25.
1.25 times 4 equals to 5.
First, solve 10x + y = -20 for y: y = -20 - 10x
Next, substitute -20 -10x for y in the second equation:
-20 - 10x = 2x^2 - 4x - 16.
Rearranging, 2x^2 + 6x + 4 = 0
Simplifying, x^2 + 3x + 2 = 0
The roots of this poly eqn are -1 and -2. Therefore, x = -1 and x = -2.
One by one, subst. these x-values into y = -20 - 10x to find the corresponding y-values.
Your answers should look like this: (-1, y) and (-2, y) (different values for y).
