Step-by-step explanation:
the right equation is :
y-y1=m(x-x1)
y+3=3(x+4)
y+3= 3x+12
y=3x+12-3
y=3x+9
Answer:
The answer is 480 cubic inches
Step-by-step explanation:
3 times 4 is 12 and 12 times 5 is 60 and 60 time 8 is 480
Answer: x=3
Step-by-step explanation:
3x + 5 = 14
Subtract 5 from both sides
3x=9
Divide both sides by 3 to get x alone
x=3
The large triangle is an isosceles since both angles at the base each equal 42°.
In an isosceles triangle the altitude z is at the same time median , then it bisects the opposite side in the middle . So w = 120/2 = 60
Now let's calculate z:
tan 42° = (opposite side) / (adjacent side) = z/60
tan 42° = 0.9,
0.9 = z/60 and z = 54
