Answer:
z=(sqrt(10)-1)/2 or z= -(sqrt(10)-1)//2
Step-by-step explanation:
To complete the square, the last term has to be 1. So adding 10 to both sides, we get:
4z^2+4z+1 = 10
Since 4z^2+4z+1=(2z+1)^2,
(2z+1)^2 = 10.
Taking the square root of both sides, we get
2z+1=sqrt(10) or 2z+1=-sqrt(10)
So z=(sqrt(10)-1)/2 or z= -(sqrt(10)-1)//2

Menjawab:
15cm
Penjelasan langkah demi langkah:
Keliling segitiga adalah jumlah semua sisi segitiga
P = s1 + s2 + s3
Diberikan sisi jika segitiga;
S1 = 5cm
S2 = 7cm
S3 = 3cm
Keliling = 5cm + 7cm + 3cm
Keliling = 15cm
Oleh karena itu, keliling segitiga tersebut adalah 15 cm
90 between two people and one having double than holly would give Joe (the winner) 60%
If you let x represent the number of free throws.
let y represent the number of two-point field goal.
let z represent the number of three-point shots made.
Then the correct system of linear equations is as follows:
x + 2y + 3z = 29 (The total number of points scored is 29.)
z = 3x - 29 (The number of 3-pointers was 29 less than 3 times the number of free throws.)
2y = z + 15 (Twice the number of 2-point shots made was 15 more than the number of 3-pointers.)
Solution:
This basketball player scored 10 points via free throws (10 at 1 point each), 16 points via 8 two-point shots made, and 3 points via 1 three-point shots made. So, in the choice its letter D.
