Given: Area of triangle =84 square feet
height= 4 feet greater than 4 times its base
h=4b +4
Area of triangle= 1/2 ( b) (h)
plugging for area and height
84=1/2 ( b)* (4b+4)
168=4b² +4b
4b²+4b-168=0
taking out 4 common as gcf
b²+b-42=0
factorising we get
(b+7)(b-6)=0
b=6, -7
since length cannot be negative so base =6feet
height= 4b+4 = 24+4=28 feet
Answer:
10 feet wide and 36 feet long
Step-by-step explanation:
5 x 2= 10 wide
4 x 9= 36 long
Answer:
(-2, 3), (.5, 3), (-4, -2), (-3)
Step-by-step explanation:
Lo siento, pero no hablo espanol bien. Usas un traductor, por favor.
A in the formula is going to be the coefficient for the x^2 term.
B in the formula is going to be the coefficient for the x term.
C in the formula is going to be the constant.
I will show you how to do A.
-b = 1
b^2 = 1
-4ab = -24
1 - -24 = 25
1 = 6, -4
2a = 2
6/2 = 3
-4 / 2 = -2
(-2, 3)
The answer is d= -2an+2s/n^2-n
That answer should be in a fraction form.
Answer:
Both are equal
Step-by-step explanation:
4+5 is 9 + 2 equals 11
and on the other side with 9+2, that would equal 11 as well.
