U need to find the length
7 + 7 + 18 + 18 = 50
width is 7 and length is 18
area is length x width
18 x 7 = 126 ft^2
Xy = 72
x - y = 1
x = 1 + y
(1+y)y = 72
y + y^2 = 72
y^2 + y - 72 = 0
(y-8)(y+9) = 0
y = 8 , y = - 9
x = 1 + 8
x = 9
y = 8
i am a mathematics teacher. if anything to ask please pm me
Answer:
a)7
b)15
Step-by-step explanation:
a)x-2=5
x=5+2
x=7
b)x-9=6
x=6+9
x=15
Determine if the following equations are linear or non-linear. Circle your answer and describe why. 7. 2. 3. = + y x linear non-linear. 5. 3.
5/6 * 8/1
Multiply the numerators and denominators together:
40/6
Simplify:
20/3
Convert to a mixed number:
6 2/3
