X=4 it is a vertical line
Answer:
base(b)=10 and height(h)=6
Step-by-step explanation:
From the question,
base(b)=x feet
height(h)=(x-4) feet
Area(A)=30 square feet
Now,
We know,
Area of triangle(A)=1/2*b*h
or, 30=1/2*x*(x - 4)
or, 30=1/2*x^2 -4x
or, 30*2=x^2 -4x
or, 60=x^2 -4x
or, 0 = x^2 -4x -60
or, 0 = x^2 +6x - 10x -60
or, 0 = x(x + 6) -10(x + 6)
or, 0 = (x+6) (x-10)
Either,
x+6=0. or, x-10=0
or,x= -6. or, x= 10
Since, the base of the triangle can not be negative number then, x≠ -6feet but x=10feet
Lastly,
Height(h)=X - 4
=10 - 4
=6 feet
Answer:
6+10+14+18+22+26
Step-by-step explanation:
Let n =1
4(1) +2 = 6
Let n = 2
4(2) +2 = 8+2 = 10
Let n =3
4(3) +2 = 12+2 = 14
Let n= 4
4*4+2 = 16+2=18
Let n=5
4*5+2 = 20+2 =22
Let n=6
4(6)+2=24+2=26
Sum these together
6+10+14+18+22+26
Answer:
D. An outline for a paper
Step-by-step explanation:
Think of a function like a template for numbers. You plug in numbers you know and you get a formula that is structured correctly. An outline is just like this because it is a structure for words.
