Answer with explanation:
x=the number of boxes containing red pens and
y = the number of boxes containing blue pens.
The expression which describes the number of red pen and blue pen in Boxes is
= (12 x-10)+(10 y-5)
The equivalent expression are
1.By Adding like terms
=12 x +1 0 y -10 -5
=12 x +1 0 y -15
or Using Associative Property of addition of three numbers which is
⇒a+(b+c)=(a+b)+c=(a+c)+b
= 10 y +12 x -15
or
= -15 +10 y +12 x
or
= 12 x -15 +10 y
The figure shows two triangles. To find the the area of the shaded region, you have to substract the area of the larger triangle by the area of the smaller:
1. Area of the larger triangle:
A1=bxh/2
b=5 mm
h=2mm+4mm+6mm=12 mm
Then:
A1=5 mmx12mm/2
A1=30 mm²
2. The area of the smaller triangle, is
A2=bxh/2
b=3 mm
h=4 mm
Then, you have:
A2=3 mmx4 mm/2
A2=6 mm²
3.<span> The area of the shaded region is:
A3=A1-A2
A3=30 mm</span>²-6mm²
A3=24 mm²
4. Therefore, the answer is: 24 mm²
Answer:
a cube that is 1 yard long, 1 yard wide, and 1 yard high
Step-by-step explanation:
The dimensions for a unit cube are:
<u>Please note that the units for each side MUST be the same (or if they're different, then the lengths have to be equivalent). </u>
<u />
Looking at the answer choices, we can see that the last answer choice is a 1 yd by 1 yd by 1 yd cube, therefore it is a unit cube.
