Find the value of 1415×211 Although these numbers aren't quite as nice as the ones from the example, the procedure is the same,
BabaBlast [244]

Answer:

298565

Step-by-step explanation:

Given problem,

1415 × 211

∵ Direct multiplication is quite tough so we can split the number into smaller one for making the multiplication easier,

= (1400 + 15) × (210 + 1)

By using distributive property,

= 1400 × (210 + 1) + 15(210 + 1)

Again by distributive property,

= 1400 × 210 + 1400 + 15 × 210 + 15

Simplifying,

=  294000 + 1400 + 3150 + 15

= 298565

Hence, 1415 × 211 = 298565

Help ????????????????????
IgorLugansk [536]
The perimeter of a triangle is when u add all of the sides together
(8x - 7w) + (2x + 6y) + (3y + 5w) = 
10x + 9y - 2w is ur perimeter

8w + 12x - 9y
8w + 12x - 9y
8w + 12x + 5y
8w + 12x - 9y

the 1st, 2nd, and 4th answer choices are the same....so 3 of them are equal

What are transformation possible to change f(x) to g(x) on graph linear equation
Korolek [52]

Answer:

<h2>Vertical stretch or compression and vertical shift.</h2>

Step-by-step explanation:

When we talk about the transformation of functions, we can mention stretching, rotating, dilating, shifting. However, when we want to transform linear functions, there are only two transformations that are worthy in that case, those are vertical stretch or compression and vertical shift.

Now, you may ask, why only vertical transformation? the reason behind that is because horizontal transformation would give the exact same result because it's only a straight line which we are transforming.

Another common question would be, why only two transformations? it's because with these two you can get all the results because it's a straight line.

The image attached shows examples of this.

Which ordered pair is a solution of the equation y= -5x +4......(2,14) (5, -29) (3, -19) (5, -21)
Ratling [72]

1) 2x+4y=10
3x+5y=14 .

find d2, dx2, and dy

2) Solve the system of equations algebraically and show your work.

2x + 3y = 12
2x - y = 4

3) Which of the ordered pairs (5,5),(5,0) and (-3,2) can be found in the shaded solution area for the system of inequalities below? (The ordered pair must be in the double shaded region or it is not a solution of the system.)

x+2y<6
2x+y > or equal too 9 so yea hoped this helped
