Simplify 2x(5x + 3) + 7(5x + 3)

Answers

Answer 1
Answer: use distributive property to solve.
2x(5x+3) + 7(5x+3)
1. distribute

2x•5x = 10x^2
2x•3= 6x

10x^2+6x

7•5x = 35x
7•3= 21

35x+21

2. combine like terms

10x^2+6x+35x+21

10x^+ 41x +21 [final answer]

What is Unitary Method?

A single unit's value may be determined from the values of multiple units, and multiple units' values can be determined from the values of single units using the unitary technique. We typically utilise this technique for math computations.

This approach allows us to calculate both the value of many units from the value of one unit and the value of many units from the value of one unit.

Given:

Bowser' dog food 60% meat if bowser needs 24 oz each week

let dog eat x ounces

So, 60%  represents 24

and, 100% represents x

Thus,

60 × x =100 x 24    

60x=2400

x=40

Hence, the dog eat 40 ounce of food.

The faces of a cube are numbered 1-6. if the cube is tossed once what is the probability that a prime number or a number divisible by 2 is obtained

Answers

Answer:

Prime Numbers 2, 3, 5

Divisible by 2 - 2, 4, 6

One is NOT a prime number.

So, there are 5 out of 6 numbers that are even or are prime.

This leaves only 1 number that isn't.

So, the probability is 5/6 that the number rolled will be prime or even.
