Part 24) The area is and the perimeter is
Part 26) The area is equal to
Step-by-step explanation:
Part 22) Find the perimeter and area
step 1
The area of a rectangle is equal to
we have
Remember that
When multiply exponents with the same base, adds the exponents and maintain the base
substitute in the formula
step 2
The perimeter of a rectangle is equal to
we have
substitute in the formula
Part 24) Find the perimeter and area
step 1
The area of triangle is equal to
where
Remember that
When multiply exponents with the same base, adds the exponents and maintain the base
substitute the given values
step 2
Find the perimeter
I will assume that is an equilateral triangle (has three equal length sides)
The perimeter of an equilateral triangle is
where
substitute
Part 26) Find the area
The area of a circle is equal to
where
Remember the property
substitute in the formula the given value
Answer:
SAS Postulate
Step-by-step explanation:
You can use the SAS (side, angle, side) postulate that says "if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent"
Side AB is proportionate to DE and
Side AC is proportionate to DF.
Angle A and Angle D are the same; and is between the two sides
I hope this helps.
Jean's car :
(12 1/2) / (5/12) =
(25/2) / (5/12) =
25/2 * 12/5 =
150/5 =
30 miles per gallon
Miranda's car :
(20 5/7) / (5/7) =
(145/7) / (5/7) =
145/7 * 7/5 =
145/5 =
29 miles per gallon
most fuel efficient is Jean's car....it gets 30 miles per gallon
Answer:
7
Step-by-step explanation:
6.7 rounds up to 7
Lets say w is the width of the flower bed. We can make an equation to find the area.
The length of the of the flower bed is (w+5) and the width is w.
To find the area we need to multiply the length(w+5) by the width(w) and set it equal to 84,
(w+5)(w)=84
w^2 +5w=84
Using the quadratic equation you get the solutions of 7 and -12. Since 7 is positive it is our width. Our length is 7+5 or 12.
