Answer:
i think the answer is 504
Step-by-step explanation:
multiply 36 by 21
multiply 60 by 21
subtract
Hope this helps my dude! :- )
First get them all on one side
add 7x+60 to both sides
0=x^2+17x+60
now factor
what 2 numbers mutltiply to get 60 and add to get 17?
5 and 12
0=(x+5)(x+12)
set each to zero
0=x+5
-5=x
0=x+12
-12=x
the factored form is (x+5)(x+12)=0
the solutions are x=-12 and -5
Answer:
Yes. You are correct.
Step-by-step explanation:
Tan(U) = opposite / adjactent
Tan(U) = 7*√3 / 7
Tan(U) = √3
Just off the top of my head, they look right.
U = Tan-1 (√3)
U = 60
Therefore tan(W) = 90 - 60 = 30
Set up an equation.
width = x
length = 56 - 2x
Multiplying length * width makes area. 56x - 2x^2 = Area.
y = -2x^2 + 56x
Ax^2 + Bx = C
Solve for the vertex: x = -(b/2a)
-(56/-4) = 14
width = 14 ft.
length = 56 - 2(14) = 28ft.
14*28 = 392 sq. ft.
It's 2 !!!!!!!!!!!!!!!!!!!!!!!
