Answer:
See below.
Step-by-step explanation:
Part A:
4(m + 3 + 5m) =
= 4m + 12 + 20m
4(m + 3 + 5m) =
= 4(6m + 3)
Part B:
Use the distributive property on the given expression to get the first expression.
4(m + 3 + 5m) =
= 4 * m + 4 * 3 + 4 * 5m
= 4m + 12 + 20m
Part C:
Let m = 2
a. Substitute 2 for m in the original expression:
4(m + 3 + 5m) =
= 4(2 + 3 + 5 * 2)
= 4(5 + 10)
= 4(15)
= 60
b. Substitute 2 for m in the second equivalent expression of part A.
4(6m + 3) =
= 4(6 * 2 + 3)
= 4(12 + 3)
= 4(15)
= 60
By substituting 2 for m, both expressions evaluate to 60.

Please help, They are parallelograms and help
Answer
first you need to know that the what is parallelogram?
A parallelogram is a special type of quadrilateral that has equal and parallel opposite sides.
the full form of parallelogram = base * height (b*h)
answer no 1
base = 6 ft
height = 4 ft
parallelogram= b* h= 6*4
= 24 ft
answer no 2
base = 9 yd
height = 5 yd
parallelogram= b* h= 9*5
= 45 yd
answer no 3
base = 7 inch
height = 3 inch
parallelogram = b*h
3 * 7 = 21 inch
answer no 4
base = 7 inch
height = 9 inch
parallelogram = b*h
9 * 7 = 63 inch
answer no 5
base = 10 ft
height = 2 ft
parallelogram = 10 * 2 = 20 ft
answer no 6
base = 6yd
height = 8yd
parallelogram = 6 yd * 8yd

Which triangle is BOTH scalene AND acute?
Answer:
The one highlighted in orange.
Step-by-step explanation:
We can see that it has no angles over 90 degrees, and all the sides are different lengths. That satisfies both of the restraints we have.
Hope that this helps!
The triangle in option A is both acute and scalene.
Acute Angled Triangle:The triangle in which all angles are less than 90° is called an acute-angled triangle.Scalene Triangles:The triangles having all the sides different are called scalene triangles.How to solve the given question?We need to find the triangle wherein all the angles are less than 90° and all the sides are different lengths.Hence, as per the given condition, Option A is the correct answer.Why other options are incorrect?In option B, All angles are less than 90° but two sides are equal in length, hence it is an acute isosceles triangle.In option C, All sides are different but one angle is more than 90°, hence it is an obtuse scalene triangle.In option D, All sides are different and one angle is 90°, hence it is a right-angled triangle.Learn more about triangles here:

Shawna works at a bakery. She is baking biscuits to fill an order for a customer. She has 2 3/4 cups of dough to make biscuits. She uses 3/16 of the dough for each biscuit. How many whole biscuits can she make?
**SHOW WORK PLZZ
Answer:12
Step-by-step explanation:
first i make it into a improper fraction which is 9/4, now i want to make the fraction into 16ths so i can dived it by 3/16, so now i do 16 dived by 4 which is 4 so now i need to do 9/4 times 4 which equals 36/16. now that u have the same denominators you will dived 36/16 by 3/16 and that will get u 12
Answer:
14 biscuits
Step-by-step explanation:
Since Shawna uses 3/16 of the dough for each biscuit we just need to find how many 3/16ths are in our 2 3/4 cups of dough. To do this, you can just perform the calculation:
[tex]\frac{\frac{11}{4} }{\frac{3}{16} } = 14.666667[/tex]
or
[tex]\frac{2.75}{0.1875} = 14.666667[/tex] (The decimals are just the fractions in decimal form)
We don't have enough dough to round up to 15 biscuits, so we only have enough to make 14.
