14x45=630
43×2=86
(14×45)-(43×2)= 630-86=544
there would be 544 pens left
Answer: Yes, she will have enough trim for all four sides of the square, because the perimeter of the square photo (30.98 inches) is less than 32 inches of trim she has.
Step-by-step explanation:
The formula for calculate the area of a square is:

Where "s" is the lenght of any side of the square.
The formula for calculate the perimeter of a square is:

Where "s" is the lenght of any side of the square.
We know that that the area of the photo is 60 square inches, therefore, we can solve for "s" from the formula
and find its value:

Substituting the value of "s" into the formula
, we get that the perimeter of the photo is:

Therefore, since Alicia has 32 inches of trim and
, we can conclude that she will have enough trim for all four sides of the square.
Answer:
Step-by-step explanation:
Xét tam giác DAB có: P là trung điểm AD, M là trung điểm AB
=> MP là đường trung bình của tam giác DAB => MP//BD và MP=
BD (1)
Xét tam giác DBC có: N là trung điểm DC, Q là trung điểm BC
=> QN là đường trung bình của tam giác DBC => QN//BD và QN=
BD (2)
Từ (1) và (2) => vecto MP song song cùng chiều với vecto QN
và độ dài MP = độ dài QN =
BD
=> vecto MP = vecto QN
Tương tự xét các tam giác DAC và tam giác ABC => vecto MQ = vecto PN
Answer:
<h2>10</h2>
Step-by-step explanation:
Let us give a proper illustration in the number line
let H be Abby's house
and S be the school
let W be her mother's work.
kindly find attached a rough sketch of the number line for your reference
Question:<em> What value represents the difference in position between Abby's house and her mother's store?</em>
basically, the distance between two points on a number line is the difference between the points.
So the value that represents the position between Abby's house and her mother's store is the distance between the two points.
= 4-(-6)
=4+6
=10
Answer:
1. x=-7/3 + 4y/3
2. x= 6- 3y/4
Step-by-step explanation:
to isolate the variable you simply solve for it by moving all the terms which don't contain x to the right by multiplying, subtracting, adding, and dividing
