Dimensions of rectangle = 12 + x and 14 + x
(12 + x) (14 + x) = 288
x^2 + 26x + 168 = 288
x^2 + 26x - 120 = 0
(x + 30) (x - 4) = 0
x=-30, x =4
since 4 is positive
the dimensions increased by 4 feet
check the answer
12+4 = 16
14 +4 = 18
18*16 =288
Answer:
D or 6
Step-by-step explanation:
Angle G is bisected if FGHI is a square. That being the case
7x + 3 = 45 Subtract 3 from both sides
7x = 45 - 3 Combine
7x = 42 Divide by 7
7x/7 = 42/7
x = 6

4. finally press the equal sign (=)
Answer:
y=-2/3x-3
Step-by-step explanation:
y-y1=m(x-x1)
y-(-1)=-2/3(x-(-3))
y+1=-2/3(x+3)
y=-2/3x-6/3-1
y=-2/3x-2-1
y=-2/3x-3
