a parallelogram has a base of 3 feet and a height of 5 feet. The base and height will each be doubled. Will the area also be dou

navik [9.2K]

Answer:

No, doubling the base and height would actually quadruple the area,

Step-by-step explanation:

With the original measurements of b = 3 ft and h = 5 ft,

b x h = A

(3) x (5) = 15 ft

So lets say we doubled the factors:

(2)(3) x (2)(5) = A

We would end up with 60 feet, four times that of 15.

(6) x (10) = 60 ft

6 R). Express 2x2 - 8x + 5 in the form a(x + b)² + c where a, b and c are integers

mylen [45]

Answer:

$\large \boxed{\sf \ \ a = 2, \ b = -2, \ c = -3 \ \ }$

Step-by-step explanation:

Hello,

$2x^2 - 8x + 5=2(x^2-4x)+5\\\\\text{*** We notice that *** }\\\\\text{*** } x^2-4x=(x-2)^2-2^2=(x-2)^2-4\\\\\text{*** So we can write ***}\\\\2x^2 - 8x + 5=2(x^2-4x)+5=2\left( (x-2)^2-4\right)+5\\\\=2\left(x-2\right)^2-8+5=\boxed{2\left(x-2\right)^2-3}$
