Answer:
Step-by-step explanation:slope is 12
For rhombus A:
base = 7 in
area = 35 in²
Area of rhombus = b * h
⇒ 35 = 7 * h
⇒ h = 35/7
⇒ h = 5 in
Rhombus B:
height = 3*5 = 15 in
base = 7*3 = 21 in
Area = 15 * 21 = 315 in
Area of rhombus B is 9 times area of rhombus A. When the dimensions are increased to 3 times the initial dimension, area became 9 times.
Answer: 15
Step-by-step explanation: First you start by adding 2+3=5 then you multiply 5 x 3 which equals 15
Answer:
the perimeter is 30
Step-by-step explanation:
ok so lets say this
width= x
length= 2x
the area is
A= wl
or
25 = x(2x)
25= 2x^2
5 = x thats the width so we know that if we double that we get the legnth so
the legnth is 10
the perimeter is defined as:
2l +2w =p
insert the width and legnth
2(5) + 2(10) = p
10+ 20= p
p= 30
40x = x+4
x= (x+4)/40
x= x/40+4/40
x-x/40= 4/40
(40x-x)/40= 1/10
39x/40= 1/10
39x= 1/10*40
x= 4/39
