Answer:

A. 10x^{2} + 33x^{2} +19x - 12

Explanation:

(2x + 3) (5^{2} + 9x - 4)\\

Mutiply 2x by each number on the second bracket

(2x) (5^{2} ) = 10x^{3} \\(2x) (9x ) = 18x^{2} \\(2x) (- 4 } ) = -8x

Then mutiply 3 by each number on the second bracket

(3) (5^{2} )= 15x^{2} \\(3) (9x) = 27x\\(3) (-4) = -12

New equation:

10x^{3} + 18x^{2}  + -8x + 15^{2} + 27x - 12

Add all like terms

10x^{3} + 33x^{2}  + 19x - 12

Korvikt [17]

Answer:

b )  the intersection of two events

Step-by-step explanation:

Gary and Steve are both hosting . There are 50 buttons total, 15 buttons are blue and 27 buttons are red. Gary puts all of the buttons into a bag. Steve and Gary both want to wear red buttons.What is the probability ? To solve this problem, you need to understand the Multiplication Rule of Probability.This probability  means to find the probability of the intersection of two events, multiply the two probabilities.

Probability of two events occurring that is called intersection of two events. There are two different set of events , called independent and dependent events.

Independent events  event is not affected by a previous event.

A dependent event is when one event influences the outcome of another event . To find the intersection of two events, whether they are independent or dependent, multiply the two probabilities together.

hammer [34]

Answer:

150

Step-by-step explanation:

We are carrying out Addition

a) The sum of 48 and itself

= 48 + 48 = 96

b) Its half and half of the half

96 + (1/2 × 48) + (1/2 ×( 1/2 × 48)

= 96 + 24 +(1/2 × 24)

= 96 + 24 + 12

= 132

c) is added to 18

= 132 + 18

= 150

Therefore, the sum of 48 and itself, its half and half of the half is added to 18 is 150
