Which of the following are solutions to the equation below?

katrin2010 [14]

First simplify then solve.

$4x^2+20x+25=49 \\4x^2+20x-24=0 \\4(x^2+5x-6)=0 \\x^2+5x-6=0\Longrightarrow(x+6)(x-1)=0 \\\boxed{x_1=-6, x_2=1}$

We find there are two solutions. In your case the correct answers are A, C, D

Hope this helps.

You are baking brownies for your class. There are 28 total students in your class and you have baked 23 brownies. Write and solv

barxatty [35]

Answer:

2(28)=23+x

Step-by-step explanation:

There are 28 students and each student needs two brownies. You have to multiply 28 by 2 so you will have to total number on one side.

On the other you need to have the number of brownies you have at the moment and x for the number you need to bake. You want to add them because you will need to put those numbers together to get the number on the opposite side.

28x2=56 so 56=23+x. Subtract the 23 from both sides to get 33=x. x=33

To check plug 33 into x to get 2(28)=23+33. 56=23+33. 56=56

you need 33 more brownies.

So the equation would be 2(28)=23+x.

Hope that helps.

Amir buys a new car for £16470. The value of the car will depreciate by 2% each year. Work out how much amir's car will cost aft

Ronch [10]

Answer:

Amir's car will cost £10348.88 after 23 years.

Step-by-step explanation:

I finally found a UK human!

This is compound interest so you have to find a decimal multiplier and multiply that with £16470 to the power of 23.

The decimal multiplier would be 0.98. This is because you do 100% - 2% as depreciating basically means a decrease, which gives you 98% and then you divide that by 100 to get your decimal multiplier - 0.98.

16470 × $0.98^{23}$ = £10348.88

I hope that helps you!! ^-^
