$520
First, you multiply 26 by 4.
Then you multiply the product (104) by 5.
Answer:

Step-by-step explanation:
can be simplified to:

Make them have common denominators so:

Simplify:

I don't think you can simplify that fraction further so that's the answer.
Answer:x>7 or x ≤ -3
Solving the 1st inequality
-6x +14 < -28 --------------- (Collect like terms)
-6x < -28 - 14
-6x < - 42 -------------------- (Divide both sides by -6)
Note: If you decide an inequality expression by a negative value, the inequality sign changes)
-6x/-6 > -42/-6
x > 7
Solving the 2nd inequality
9x + 15 ≤ −12 ----------- (Collect like terms)
9x ≤ −12 - 15
9x ≤ −27 ------------------(Divide both sides by 9)
9
9x/9 ≤ −27/9
x ≤ -3
Bring both results together, we get
x>7 or x ≤ -3
The final result is complex (i.e. can't be combined together).

Answer:
9/16
Step-by-step explanation:


Derivative rule:


Here, n=-1, so

Evaluating this at x=-4 gives 9/16
