Answer:

9x² − 12x + 4

Step-by-step explanation:

A perfect square trinomial:

a² + 2ab +b²= (a + b)²

a² - 2ab +b²= (a - b)²

9x² − 12x + 4 = (3x)² - 2*(3x)*2 + 2² = (3x - 2)²

36b² − 24b + 16

16x² − 24x − 9

4a² − 10a − 25

Answer:

625 cm3

Step-by-step explanation:

Formula V1 * P1 = V2 * P2

V1 = 450 cm3

P1 = 125 kPa

P2 = 90 kPa

V2 = ?

V2 = (V1 * P1) / P2

V2 = (450 cm3 * 125 kPa) / 90 kPa = 625 cm3

Find x in this 45°-45°-90° triangle.<br><br><br><br> x =
Zielflug [23.3K]
Use a^2 + b^2 = c^2

the triangle must be isosceles because the two angles are the same

1.2^2 + 1.2^2 = x^2
1.44 + 1.44 = x^2
2.88 = x^2
x=6√2/5
or
x ≈1.69706

I need help with a MathsWatch question!
KIM [24]
To find the area of a circle, you do π × diameter (in this case 10). They have told you to use 3.142 as π, so you do 3.142 × 10 = 31.42. Because it's a semi-circle, you need to halve 31.42 to get 16.21, which is the answer
