romanna [79]

Answer:

$\huge\boxed{(d+7)(d-7)=d^2-49}$

Step-by-step explanation:

$\bold{METHOD\ 1:}\\\\(d+7)(d-7)\qquad|\text{use}\ (a+b)(a-b)=a^2-b^2\\\\=d^2-7^2=d^2-49\\\\\bold{METHOD\ 2:}\\\\(d+7)(d-7)\qquad|\text{use FOIL}\ (a+b)(c+d)=ac+ad+bc+bd\\\\=(d)(d)+(d)(-7)+(7)(d)+(7)(-7)\\\\=d^2-7d+7d-49\qquad|\text{combine like terms}\\\\=d^2+(-7d+7d)-49\\\\=d^2-49$

What are the dimensions of a rectangular box with a volume of 50b 3 + 75b2 - 2b - 3?

Inessa [10]

Answer:

$\large\boxed{(2b+3)\times(5b-1)\times(5b+1)}$

Step-by-step explanation:

The formula of a volume of a rectangular box:

$V=lwh$

l - lenght

w - width

h - height

$V=50b^3+75b^2-2b-3=25b^2(2b+3)-1(2b+3)\\\\=(2b+3)(25b^2-1)=(2b+3)(5^2b^2-1^2)\\\\=(2b+3)\bigg((5b)^2-1^2\bigg)\qquad\text{use}\ a^2-b^2=(a-b)(a+b)\\\\=(2b+3)(5b-1)(5b+1)$

Therefore the dinemsions of thisp prism are:

$(2b+3)\times(5b-1)\times(5b+1)$

hoa [83]

<h3>To find value of x</h3>

Formula applied:

Exterior angle=Sum of interior angles

Answer:

x=66⁰+45⁰

x=111⁰✔

<h3 />

<h3>To find value of z:</h3>

Formula applied:

Exterior angle=Sum of interior angles

Answer:

119⁰=43⁰+z⁰

119⁰-43⁰=z⁰

z⁰=76⁰✔

<h3>To find value of y:</h3>

∠1+66⁰=180⁰(L.P)

∠1=180⁰-66⁰

∠1=114⁰

Formula used:

Sum of angles of a triangle =180⁰

Answer:

∠ 1+30⁰+y⁰=180⁰

114⁰+30⁰+y⁰=180⁰

y⁰=180⁰-144⁰

y⁰=36⁰✔
