Just replace the x in the question with -2, and the y with 2.
Therefore, you're doing ((-2)(2²))/7 which is -2 times 2 squared all over 7.
-2 × 2² = -8
-8/7 is your answer.
The answer is 6 to your question, but why does my answer have to be at least 20 characters long?
Answer:
10power 15
Step-by-step explanation:
You keep the base, and you multiply the powers which means
5✖️3=15
base=10
10power 15
Given equation: -9-5(1-7y)=-20
Step 1) Distributing -5 over (1-7y), we get
-9 -5 +35y = -20.
Step 2) Now, combining like terms (-9-5 =-14) on left side, we get
-14 +35y = -20.
Step 3) Now, we need to get rid -14 form left side.
In order to get rid -14 from left side, we need to add 14 on both sides.
-14+14 +35y = -20+14
35y = -6.
Step 4) Dividing both sides by 35, we get
35y/35 = -6/35.
<h3>y = - 6/35.</h3>
Answer:
9x(3x-2) (3x+2)
Step-by-step explanation:
9(9x³ - 4x)
9x(9x² - 4)
Since both terms are perfect squares factor using the difference of squares formula, a² - b² = (a + b) (a - b)
Therefore, 9x(3x-2) (3x+2)
