Answer:
comunest hahahahaha
Step-by-step explanation:
A = a^2
112 = a^2
sqrt 112 = a
sqrt 16 * sqrt 7 = a
4 sqrt 7 = a
so 4 sqrt 7 is the length of each side
B and C would be the answers because 25/100 is 0.25, and to work out 25% of 64, you do 64 times 0.25
Answer:
Step-by-step explanation: For example, if we have matrix A whose all elements in the first column are zero. Then, by one of the property of determinants, we can say that its determinant is equal to zero. Hence, A would be called as singular matrix. Note that singular matrices are non-invertible (their inverse does not exist).
Answer:
A
Step-by-step explanation:
Slope = (3+6)/(-4+1)
= 9/-3
= -3
Y=mx+b
-6= -3×-1 +b
-6 = 3 +b
b = -9
