Answer:

36+30 = 6(6+5)

Step-by-step explanation:

We just simply expand the brackets:

6×6=36

6×5=30

30+36=76

so 76-36=30

So the missing number was 30

Answer:

The answer is 8.6×10¹⁴

Step-by-step explanation:

You can evaluate it :

$(4.3 \times {10}^{8} ) \times (2.0 \times {10}^{6} )$

$= (4.3 \times 2.0) \times ( {10}^{8} \times {10}^{6} )$

$= 8.6 \times {10}^{8 + 6}$

$=8.6 \times {10}^{14}$

Multiply. (2x2 + 4x - 3)(x2 - 2x + 5)

BigorU [14]

For a moment, let $y=x^2-2x+5$ . Then by the distributive property,

$(2x^2+4x-3)p=2x^2p+4xp-3p$

Again by the distributive property,

$2x^2p=2x^2(x^2-2x+5)=2x^4-4x^3+10x^2$

$4xp=4x(x^2-2x+5)=4x^3-8x^2+20x$

$-3p=-3(x^2-2x+5)=-3x^2+6x-15$

Taking everything together, we get

$(2x^2+4x-3)(x^2-2x+5)=(2x^4-4x^3+10x^2)+(4x^3-8x^2+20x)+(-3x^2+6x-15)$
$(2x^2+4x-3)(x^2-2x+5)=2x^4-x^2+26x-15$

wariber [46]

Answer:

(B). A physical change takes place that causes molecules to move faster

Step-by-step explanation:

When a bar of chocolate melts its physical form is changed, there is no difference in its chemical composition as it is still same.

When the chocolate bar was frozen its molecules were held strongly, and they were barely moving, whereas when it melts the molecules are more free to move now.
