Answer:
Step-by-step explanation:
(a + b)² = a² + 2ab + b²
a = 15y
2ab = 12x³y
2* 15y*b = 12x³y
(15y + 0.4x³)
Answer:
<h2>∗ = 0.4x³</h2>
Step-by-step
We have :
2×(0,4)×15=12
(0,4)^2=0,16
(15y + ∗)^2 = 225y² + 12x³y + 0.16x⁶
= (15y)² + 2×(15y)×(0.4x³) + (0.4x³)²
then
∗ = 0.4x³

Answer:
-2.33
Step-by-step explanation:
Let the number be denoted as "x"
-45x + 12 = 117
-45x = 117-12
-45x = 105
x = 105/-45
x= -2.33
The inequality should be
N= 12
Subtract 70.85 and 7.25 which equals 63.6. Then take 63.6 divided by 5.3 and it equals 12! Hope this helps.
Answer:
Step-by-step explanation:
76
sides of right angle triangle follows Pythagoras theroem
which states
a^2 +b^2 = c^2
where a , b and c are sides of right angle triangle.
here none of options do not follow this.
so answer is option D
