-11-5a=6(5a+4) .... Distribute the 6 to 5a and 4
-11-5a=30a+24 .... Subtract 30a from both sides
-11-5a-30a=24 .... Add 11 from both sides
-5a-30a=24+11 .... Add like terms
-35a=35 .... Divide -35a from both sides
a=-1 .... Final answer
Answer:
c = -5
Step-by-step explanation:
Plug in -5 to c in the equation:
c² - 25 = 0
(-5)² - 25 = 0
Simplify. First, solve the power, then solve the subtraction:
(-5)² - 25 = 0
(-5 * -5) - 25 = 0
(25) - 25 = 0
0 = 0 (True)

Step-by-step explanation:
pemdas
(1.2 x 10 ^13) - (4 x 10 ^11)
10^13 = 10,000,000,000,000 put that in scientific notation to make it simpler do same for 10 ^11
10 x 10^13
(1.2 x 10 x 10^13) - ( 4 x 10 x 10^11)
now solve the first equasion
12,000,000,000,000 - 400,000,000,000
subtract
11,600,000,000,000
Answer:
C. 9.5
Step-by-step explanation:
The Pythagorean Theorem: a^2 + b^2 = c^2.
4^2 + 8.6^2 = c^2
16 + 73.96 = c^2
c^2 = 89.96
c = 9.4847....
