Answer:
147.03 cm²
Step-by-step explanation:
Area of a parallelogram:
A = bh
A - area
b - base
h - height
From the figure,
Base = 16.9 cm
Height = 8.7 cm
A = (16.9)(8.7)
A = 147.03 cm²
Area of a rectangle=lenght x width.
width=x
length=x+3
we can suggest this equation:
x(x+3)=40
x²+3x=40
x²+3x-40=0
we solve this square equation:
x=[-3⁺₋√(9+160)] / 2
x=(-3⁺₋13)/2
we have two solutions:
x₁=(-3-13)/2=-8 this solution isn´t valid.
x₂=(-3+13)/2=5
lenght=x+3=5+3=8
Answer: the lenght, in inches, of the rectangle is 8 .
(2) 8
Answer:
x=24/7
Step-by-step explanation:
3(x+2)+4(x-5)=10
3x+6+4(x-5)=10
3x+6+4x-20=10
7x+6-20=10
7x-14=20
7x=24
x=24/7
Answer:
8 units
Step-by-step explanation:
If we start at point Q and count down to point R we find the distance of segment QR.
-> Since this is on a coordinate plane, we can also use the distance formula
d =
d =
d =
d =
d =
d = 8 units
