F(x) = x^2 - 3x+ 5 g(x) = 2x^2 - 4x - 11 what is h(x) = f(x) + g(x)
iogann1982 [59]

Hey there! :)

Answer:

h(x) = 3x² - 7x - 6

Step-by-step explanation:

Calculate h(x) by adding the two polynomials:

h(x) = f(x) + g(x):

h(x) = x² - 3x + 5 + 2x² - 4x - 11

Combine like terms:

h(x) = 3x² - 7x - 6

Couldn't do this one help needed
Paladinen [302]

Answer:

shown below.

Step-by-step explanation:

v = 150 since 180 - 30

for w we need 2y and x. the base angles of the triangle are 30 and 50 therefore x = 100. 2y = 30 because corresponding angles. ergo, w = 50

x = 100

y = 15

z = 50

On selling 250 cascades, a man had an equal gain to the selling price of 25 cascades. Find his gain percent
Jet001 [13]

Answer:

11.11%

Step-by-step explanation:

The selling price is 250

The cost price is 250-25

= 225

Therefore the gain can be calculated as follows

=250-225x/225x×100

1/9 ×100

= 0.1111×100

= 11.11%

Hence the gain is 11.11%
