Given:
The expression is:
To find:
The factor of the given expression by GCF.
Solution:
It is given that,
The terms of the given expression are . The greatest common factor of these terms is 3.
So, taking out the GCF, the given expression can be rewritten as:
Therefore, the factor form of the given expression by GCF is .
Distance travelled in 14 days is : 456.4 km
And if he travels same Distance each day, so let the Distance travelled on each day be x
According to question ~
So, he travels 32.6 km per day
Answer:
a, c) see below
b) trapezoid
d) 80 square units
Step-by-step explanation:
a, b, c) See the attached plot. The different-length horizontal bases make this a trapezoid.
__
d) The area of the original is ...
A = (1/2)(b1 +b2)h = (1/2)(1+4)(2) = 5
Dilation by a factor of 4 multiplies the area by a factor of 4² = 16.
The area of the larger trapezoid is ...
5 × 16 = 80 . . . . square units
__
Of course, you can use the area formula, too:
A = (1/2)(b1 +b2)h = (1/2)(4 +16)(8) = 80 . . . . square units
Answer:
The area needed to be painted is approximately 301.44 square inches.
Step-by-step explanation:
The shape of a donut is represented by two concentrical circles, whose area is described by the following formula:
(Eq. 1)
Where:
- Total area of the donut, measured in squared inches.
- Area of the greater circle, measured in square inches.
- Area of the lesser circle, measured in square inches.
By using the definition of the area of the circle, we expand the equation above:
(Eq. 1b)
If we know that ,
and
, the area needed to be painted is:
The area needed to be painted is approximately 301.44 square inches.
