Answer:
35y - 67
Step-by-step explanation:
8(5y - 8) - (5y + 3)
Multiply the 8 with what is in the parentheses.
40y - 64 - 5y + 3
Subtract like terms.
35y - 67
Tan(x)= sin(x)/cos(x), therefore, substitute sin(x)/cos(x) in the expression:
=(cos(x)(sin(x)/cos(x))-1)/cos^2(x)
simplify the 2 cos(x):
=(sin(x)-1)/cos^2(x)
Sin^2(x)+ cos^2(x)=1, sin^2(x)-1=- cos^2(x), substitute in the expression:
= -cos^2(x)/cos^2(x)= -1
Answer:
C. y=11
Step-by-step explanation:
6y-6=4y+16
6y=4y+22
2y=22
y=11
Answer:
A.1 square and 4 triangles
Step-by-step explanation:
A pyramid has sides that are triangular faces and a base. In a square pyramid, the base is a square.
The net therefore has 1 Square and 4 Triangles.
A net is given in the attached diagram:
