What is the value of the expression when a = 5 and b = 2? 2a+b−3
A. 6

B. 9

C. 11

D. 24

9

Hi there !

2a + b - 3 =

replace a = 5 ; b = 2

= 2(5) + 2 - 3

= 10 + 2 - 3

= 12 - 3

= 9

Good luck !

9

2a and b - 3 = ?

a = 5 ; b = 2

2(5/a) + 2/b - 3

Now we solve this.

10 + 2/b - 3

Subtract 3.

12 - 3

The answer is 9.

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.

step-by-step explanation:

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
