Find 5g(x)-f(x) given f(x)=9x^2+7x and g(x)=2-x ^2 means there’s a 2 over top that number please show work

- 9x² - 12x + 10

Step-by-step explanation:

5g(x) - f(x)

= 5(2 - x) - (9x² + 7x) ← distribute both parenthesis

= 10 - 5x - 9x² - 7x ← collect like terms

= - 9x² - 12x + 10

last option: rhombus or kite

step-by-step explanation:

a kite and rhombus have the same shape. as we don't have any specific formula for the calculation of area of kite. the diagonals are used to calculate the area of a kite or rhombus.

the formula for area of rhombus is given by:

here, d_1 is the first diagonal and d_2 is the second diagonal.

so,

last option is the correct answer ..
