Convert to factored form y = x² + 6x

steposvetlana [31]

Convert to factored form is:

$y = x(x + 6)$

Solution:

Given that,

$y = x^2 + 6x$

We have to convert to factored form

Factored form means writing terms in multiplication. i.e as a product

From given,

$y = x^2 + 6x$

Factor out x from above given expression

$y = x(x + 6)$

Here, the given equation is written as product of "x" and (x + 6)

Thus the factored form is found

Find the area of the triangle.

KengaRu [80]

Answer:

10 Square feet or square meter

Area of a triangle = bh / 2

b represents the base which is 4

h represents the height which is 5

bh / 2 = 4 × 5 / 2

Area = 20 / 2

Area = 10

Perform the following calculations without rewriting the numbers in decimal form.

RSB [31]

Answer:

Answer will be $140\times 10^{13}$

Step-by-step explanation:

We have to perform the calculation $(1.42\times 10^{15}-2\times 10^{13})$ without changing into decimal

$1.42\times 10^{15}$ can be written as $142\times 10^{13}$

So $1.42\times 10^{15}-2\times 10^{13}=(142\times 10^{13}-2\times 10^{13})$

Now taking $10^{13}$ common

$10^{13}(142-23)=140\times 10^{13}$
