Answer:
77y-44
Step-by-step explanation:
when you expand this type of equations you just multiply the coefficient of y and the number by -11
so:
-11*4=-44
-11*-7=77 (note: negative multiplied by negative equals positive)
so the equation now became
-44+77y
exchange places now its:
77y-44
3* tan(x) - root(3) = 0
3* tan(x) = root(3)
tan(x) = root(3) /3 = 0.577
x = tan^-1(0.577) or atan(0.577)
x = 30 degrees

i think letter D because it's same
The material needed to make 1 kite is 144 square inches and for 3 kites she need 432 square inches of the material.
Step-by-step explanation:
Diagonals of the kite = 16 inches and 18 inches
Area of the kite = (16 x 18) /2
= 144 square inches
Area of 3 kites = 3 x 144
= 432 square inches.
The material needed to make 1 kite is 144 square inches and for 3 kites she need 432 square inches of the material.
