Answer:
500
Step-by-step explanation:
(4 feet wide), 12 feet in length. 4*3=12 4*12=48
Answer:
See below. A=45 p=39.64
Step-by-step explanation:
Hi = 9 squares (h)
Gh= 14 squares. (b)
Area of a triangle = 1/2 bxh
1/2 14 x 9
7x9= 45.
Area =45 squares.
Perimiter
A= side hi (9)
B= side gh (14)
C= side gi (unknown)
A^2 + b^2 = c^2
9^2 + 14^2 = 277
C^2 = 277
Square root of 277 =c
C length =16.64 squares
A+b+c = perimeter
9+14+16.64 = 39.64 squares.
Sorry I cannot see the units of measure in the photo
X^2-9=0 add 9 to both sides
x^2=9 take the square root of both sides
x=±3
Answer:
x=-48
Step-by-step explanation:
Add 4 to both sides and then multiply both sides by 3.
