5)(7x-10)(x+1)
6)(7n-1)(n-9)
Step-by-step explanation:
1) Factors of -5 that add up to 4
2) Factors of --12 that add up to -1
3) Factors of 4 that add up to -5
4) Factors of -5 that add up to 4
5) 7-3x-10
7+7x-10x-10
7x(x+1)-10(x+1)
(7x-10)(x+1)

7-63n-n+9
7n(n-9)-(n-9)
(7n-1)(n-9)
Answer:
2/5
Step-by-step explanation:
The experimental probability is
P (heads) = number of heads/ total tosses
= 8/20
= 2/5
If it starts with 0.12 it is false.
But if it starts with 0.009 it is true.
The measure of the angle B is 30 degree after applying the sin law of triangle.
<h3>What is the triangle?</h3>
The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have a triangle shown in the picture:
We can apply the sin law of the triangle to find the angle B
SinB = 0.499
B = 29.99 ≈ 30 degree
Thus, the measure of the angle B is 30 degree after applying the sin law of triangle.
