I am pretty sure it is Point D
(3) is the base of the new equation
(x + 5) is the answer of the new equation
(2) is the exponent on base (3)
;The new equation after simplifying is...,
; 3^2 = x + 5
; 9 = x + 5
; x = 9 - 5
;Hence...x = 4
Answer:Let x = pay per hour as a carpenter and y = pay per hour as a blacksmith
Last week she worked 12 hours as a carpenter
earning 12x dollars
and 20 hours as a blacksmith
earning 20y dollars
and earned a total of $860
and those two things add up to 860.
Do the same with the other sentence, giving you a second equation.
Step-by-step explanation:
n=-2 i got this answer because i combined like terms first like 2n-n
we get just n after
and then, we subtract the 5 from both sides to get it on the opposite side of the equal sign.. we get x=-2
To find the 3rd side of a triangle, use the pythagorean theorem.
a^2 + b^2 = c^2
a = 11
b = ?
c = 23
11^2 + b^2 = 23^2
121 + b^2 = 529
b^2 = 408
b = √408 = 2 √102 = 20.199, 20.2, or 20
The answer can be any of those.
