Solve for x in the equation x squared + 2 x + 1 = 17.

Answers

Answer 1
Answer:

Answer:

Step-by-step explanation:

x^2 + 2x + 1 = 17

x^2 + 2x = 17 - 1

x^2 + 2x = 16

x^2 + 2x + 1 = 16 + 1

(x + 1)(x + 1) = 17

(x + 1)^2 = 17

x + 1 = sqrt 17

x = -1 (+ - ) sqrt 17

x = -1 + sqrt 17 or x = -1 - sqrt 17

Answer 2

x = -1 + square root 17

Andre has 4 times as many model cars as Peter, and Peter has one-third as many model cars as Jade. Andre has 36 model cars. Write and solve an equation to find how many model cars Peter has. Using your answer from part a, write and solve an equation to find how many model car Jade has.

Answers

First solve what is probably 'part A.'
Peter has 36 ÷ 4; Peter has 9 model cars. Jade has 3 times as many as Peter; Peter has 1/3 as many as Jade, so 9 x 3 = 27, so Jade has 27 cars.

1st equation: 36 ÷ 4 = 9 -OR- 36 x 1/4 = 9
2nd equation: 9 x 3 = 27 -OR- (36 x 1/4) x 3 = 9
(36/4)3 = 9 would also work. I think the 1st equations would be best... just giving some choices...

You spend $10 on office supplies out of the $25 budget what percent of your budget did you spend

Answers

Answer:

You spent 40% of your budget on office supplies.

Step-by-step explanation:

1. First take the total budget:

2. Then take the money you spent on office supplies and divide it by the total budget to find the ratio you spent:

3. Finally multiply the ratio by a hundred to find the percentage of the budget you spent on office supplies:

%

Therefore, you spent 40% of your budget on office supplies.

The simplest way to find percent is to take the partial number, divide by the whole number, and multiply the answer by 100%.

= 0.4

0.4 x 100% = 40%.
