Anna drives her car at a speed of 70 km per hour. How much distance will she cover in 3 hours 30 minutes?

Tresset [83]

Answer:

$\sf \: 245 km$

Step-by-step explanation:

$\sf Speed \: of \: the \: car = 70 km/h$

$\sf Time \: taken = 3 \: hours \: 30 \: minutes$

$= \sf 3 \frac{1}{2} \: hours$

$\sf = \frac{7}{2} \: hours$

$\sf Distance = Speed \times Time$

$\sf Distance = 70 \times \frac{7}{2} \: km$

$\sf Distance = 245 \: km$

Hence, Anna will cover 245 km in 3 hours 30 mins.

Find each product. 1. 2x(x^2-6x+3) 2. 2a^2(5b^2 + 3ab + 6a + 1)

hoa [83]

Given:

The expressions are:

$2x(x^2-6x+3)$

$2a^2(5b^2+3ab+6a+1)$

To find:

The product of each expression.

Solution:

According to the distributive property of multiplication over addition, we get

$a(b+c)=ab+ac$

The first expression is:

$2x(x^2-6x+3)$

Using distributive property of multiplication over addition, we get

$2x(x^2-6x+3)=(2x)(x^2)+(2x)(-6x)+(2x)(3)$

$2x(x^2-6x+3)=2x^3-12x^2+6x$

Therefore, the product of $2x(x^2-6x+3)$ is $2x^3-12x^2+6x$ .

The second expression is:

$2a^2(5b^2+3ab+6a+1)$

Using distributive property of multiplication over addition, we get

$2a^2(5b^2+3ab+6a+1)=(2a^2)(5b^2)+(2a^2)(3ab)+(2a^2)(6a)+(2a^2)(1)$

$2a^2(5b^2+3ab+6a+1)=10a^2b^2+6a^3b+12a^3+2a^2$

Therefore, the product of $2a^2(5b^2+3ab+6a+1)$ is $10a^2b^2+6a^3b+12a^3+2a^2$ .
