Answer:
Y || Z
Step-by-step explanation:
We know that Y⊥B, and Z⊥B, which means both Y and Z are perpendicular to B, meaning that they both create 90° angles with B, and from that, we can make the conclusion that Y || Z
Answer:
130 minutes total and 2 hours and 10 minutes
Step-by-step explanation:
Its correct
Let's work this problem out!
First: 5(x) - 26 - x + 50 = ?
Second: 4(x) - 76 = ?
Third: 4 = ?
↑
(Solve Step 3)
Fourth: x - 19 = 0
↑
(Add the number 19 to each of your sides for Step 4)
Finally we get to your answer
19 + 0 = 19 ; 19 - 19 = 0
So, therefore the value of "x" is 19
3ˣ (x² - 3)
Basically, just multiply everything together.
Step 1 : 3x × x² = 3x³ because when multiplying exponents, all you're really doing is adding them on top. So, x + 2x = 3x! But, they are exponents, so you get 3x³.
Step 2 : 3x ˣ × (-3) = -9ˣ
Now, our new question is : 3x³ - 9x
You wouldn't simplify this because x³ is NOT the same as x.
