Answer:(2x - 5)(3x + 1)
Step-by-step explanation:
6x^2 - 13x - 5
6x^2 + 2x - 15x - 5
2x (3x + 1) - 5 (3x + 1)
(2x - 5)(3x + 1)
Answer:
D. 11.6 cm
Step-by-step explanation:
The missing length of the right angled triangle can be calculated using Pythagorean Theorem as shown below:
Where,
a = x cm
b = 11 cm
c = 16 cm
Thus:
(nearest tenth)
Answer:
x = 60°
y = 72°
z = 48°
Step-by-step explanation:
x = 180 - p = 180 - 120 = 60
Since y;z = 3:2 , 2y = 3z or z = 2y/3
Now, x + y + z = 180
60 + y + 2y/3 = 180 Multiply thru by 3 to remove the fraction
180 + 3y + 2y = 540
180 + 5y = 540
5y = 360
y = 72
z = 2(72)/3 = 48
Check: 60 + 72 + 48 = 180
Answer:
Geometric Sequence
Step-by-step explanation:
In this case it is Geometric Sequence as it has a common ratio of 5
Formula for nth term: a(n) = ar∧n-1
so if we take the third term we will calculate as follows:
50 = 2(r)∧3-1
50÷2 = r∧2
√25= r
r=5
At least 15 b/c is you add QWERTY to -12, you get zero and adding 5 to get 15 in total.
