I'm confused. Can someone help me out with this problem step-by-step using the P = 2L + 2W formula?

german

We can't use P = 2L + 2W because the sides have different lengths.

P = a + b + c + d

a = x

b = 2x

c = 2x - 2

d = x + 5

P = x + 2x + (2x - 2) + (x + 5)

P = x + 2x + 2x - 2 + x + 5

P = 6x + 3

if x = 4:

P = 6 · 4 + 3

P = 24 + 3

P = 27

I need to find the simplest form of 88 ---- 90

hram777 [196]

Given

$\frac{88}{90}$

So,

$\frac{88}{90}=\frac{2\cdot44}{2\cdot45}=\frac{44}{45}$

So, the simplest form of 88/90 is 44/45

Please Help! Evaluate the function at each specified value of the independent variable and simplify. (If an answer is undefined,

Licemer1 [7]

Answer:

Given:

g(t) = 5t² − 8t + 3

Find the following

g(2)

g(2) = 5(2²) - 8(2) + 3 = 20 - 16 + 3 = 7

g(t - 2)

g(t - 2) = 5(t - 2)² - 8(t - 2) + 3 = 5t² - 20t + 20 - 8t + 16 + 3 = 5t² - 28t + 39

g(t) - g(2)

g(t) - g(2) = 5t² − 8t + 3 - 7 = 5t² − 8t - 4

The length of the base of a triangle is twice its height. if the area of the triangle is 196 square kilometers, find the height

NISA [10]

Area = 1/2 x base x height

Let the height be x.
Height = x
Base = 2x

Area of triangle = 1/2 x base x heght

Plug base and height into the variables:
(1/2)(2x)(x) = 196

Combine like terms:
x² = 196

Square root both sides:
x = 14

Find Base and height:
Base = x = 14 km
Height = 2x = 2(14) = 28 km

Answer: Height = 28km
