The answer is a = 2.25.
Simplifying
7 + -4(3a + -5) = 0
Reorder the terms:
7 + -4(-5 + 3a) = 0
7 + (-5 * -4 + 3a * -4) = 0
7 + (20 + -12a) = 0
Combine like terms: 7 + 20 = 27
27 + -12a = 0
Solving
27 + -12a = 0
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-27' to each side of the equation.
27 + -27 + -12a = 0 + -27
Combine like terms: 27 + -27 = 0
0 + -12a = 0 + -27
-12a = 0 + -27
Combine like terms: 0 + -27 = -27
-12a = -27
Divide each side by '-12'.
a = 2.25
Simplifying
a = 2.25
Answer:
14 in and 16 in
Step-by-step explanation:
Given data
We are told that the aquarium has the shape of a cube
the first specification is
2744 cubic inches
volume= 2744 cubic inches
length = ∛2744
length= 14 in
the second specification is
4096 cubic inches
volume= 4096 cubic inches
length = ∛4096
length= 16 in
Hence the possible lengths are
14 in and 16 in
Answer:
<em>48</em>
Step-by-step explanation:
AC = 10
DC² = 10² - 6² = 64
DC = 8
= 6 × 8 = 48
