Convert to the product of multiplication<br>a^2-b^2-4b-4

kirill [66]

$a^2-b^2-4b-4$ in form of multiplication is $(a-b)(a+b)-4(b+1)$ .

<u>Step-by-step explanation:</u>

We know that factors are the numbers that are being multiplied together . As 6532*7 = 45724 .Here 6532 & 7 are the factors and 45724 is product of the factors .

Here , we need to convert to the product of multiplication

a^2-b^2-4b-4 or , $a^2-b^2-4b-4$ :

⇒ $a^2-b^2-4b-4$

We know by identity that , $p^2-q^2 = (p-q)(p+q)$

⇒ $(a-b)(a+b)-4b-4$

Taking common term out as -4 :

⇒ $(a-b)(a+b)-4(b+1)$

Therefore , $a^2-b^2-4b-4$ in form of multiplication is $(a-b)(a+b)-4(b+1)$ .

What is 4 to the 2/3 power

Anna11 [10]

$\bf a^{\frac{{ n}}{{ m}}} \implies \sqrt[{ m}]{a^{ n}} \qquad \qquad
\sqrt[{ m}]{a^{ n}}\implies a^{\frac{{ n}}{{ m}}}\\\\
-------------------------------\\\\
4^{\frac{2}{3}}\implies \sqrt[3]{4^2}\implies \sqrt[3]{(2^2)^2}\implies \sqrt[3]{2^4}\implies \sqrt[3]{2^{3+1}}\implies \sqrt[3]{2^3\cdot 2}
\\\\\\
2\sqrt[3]{2}$

Sarah is building a set of four shelves each shelf will have two supports in the shape of right isosceles triangle's each shelf

Rama09 [41]

Answer:

784 in² of wood

Step-by-step explanation:

Sarah needs two supports by shelf, and she will build 4 shelves

then she will need 8 supports

Now each support is a right isosceles triangle.

Area of a triangle is

A(t) = 1/2 *b*h where b is the base and h is the heigh of the triangle.

A right isosceles triangle has two sides ( base and heigh equals) and in our particular case are equals to 14 in, therefore

A(t) = 1/2*14*14

A(t) = 98 in²

Sarah needs 8 pieces of 98 in² she needs

A = 8*98

A = 784 in² of wood
