Answer:
a=-6
Step-by-step explanation:
4= 6/a + 5
Subtract 5 from each side
4-5= 6/a + 5 -5
-1 = 6/a
Multiply by a on each side
-1*a = 6/a *a
-a =6
Multiply by -1
a= -6
Answer:
-5^ -1 = 1/(-5) = -1/5
-1/y^(-4) = -(1/(1/y^4)) = -y^4
5^4 x 5^7 = 5^(4 + 7) = 5^11
Hope this helps!

Answer:
(9 × 100) + (2 × 1) + (6 × 0.1) + (4 × 0.001)
Step-by-step explanation:
I am pretty sure
First we will subtract 16 acres from total land 349 acres.
349-16=333 acres
Now divide 333 by 3
Answer will be 111 lots of 3 acres.
Answer:
(x + 9)(x + 3)
Step-by-step explanation:
Factor 27 so that the factors, when combined, will equal 12:
x² + 12x + 27
x 9
x 3
(x + 9)(x + 3) is your answer.
Check: Use the FOIL method. Multiply the first two terms, the outside terms, the inside terms, and then the last two terms. Combine like terms:
(x + 9)(x + 3) = x² + 3x + 9x + 27 = x² + 12x + 27 (√)
