The base length of the triangle is 10 ft. and the height of the triangle is 20ft.
Step-by-step explanation:
Height = base + 10
Area = 100 square ft
Area of a triangle= (1/2) (b) (h)
100 = (1/2) (b) (b + 10)
200 = b(b) + 10b
b(b) + 10b - 200 = 0
b(b) + 20b - 10b - 200 = 0
b ( b + 20) -10(b + 20) = 0
(b-10) (b+20) =0
b = 10 (or) b = -20
Here b is the length and cannot be negative.
So, b = 10ft
h = b + 10
h = 10 + 10
h = 20 ft.
The base length of the triangle is 10 ft. and the height of the triangle is 20ft.
It should be the first one, or 3x, I’m pretty sure because x is going to be the amount that he has and he has 3 times the amount or something
Hello!
Here a graph of the slope!
Hi maybe take a picture of the question it sounds like you are trying to solve a polynomial but the only factors of 16 are
1 and 16 -1and -16 2 and 8 and -2 and -8 i hope
But I’d you are solving a polynomial try using the quadratic formula doing something like this
First find the LCD of the denominators then convert the fractions. Then you can subtract.
for example
2/7 - 1/4
LCD of 4 and 7 is 28 so we convert to fractions with denominator 28
1/4 = 1*7 / 4*7 = 7 /28
2/7 = 2*4 / 7*4 = 8/28
so 2/7 - 1/4 = 8 /28 / 7/28 = 1/28 answer
