Answer:
(a) 1.2b
(b) 1.4h
(c) A = 1.68bh
(d) 68%
Step-by-step explanation:
(a) If 20% of b is added to b, you have ...
b + 0.20b = 1.2b
__
(b) Similarly, if 40% of h is added to h, you have ...
1.4h
__
(c) The area of the new rectangle is the product of the new dimensions:
A = (1.2b)(1.4h)
A = 1.68bh
__
(d) The original rectangle area is A = bh, so the percentage change can be computed as ...
(A'/A -1)×100% = ((1.68bh)/(bh) -1)×100% = (1.68 -1)×100% = 68%
The given increases in base and height increase the area by 68%.
Answer:
n = - 3
Step-by-step explanation:
Slope line r: (5-1)/(3+1) = 4/4 = 1
Slope of the perpendicular line: -1
p=(-4,4)
y-intercept: 4 - (-1)(-4) = 4 - 4 = 0
y = -x
(3,n) x = 3 and y = n
n = - 3
