Problem 1<br> 4x+8=12<br> Problem 2<br> 2x+7=15
Anuta_ua [19.1K]
The answer to the first problem is x=1
The answer to the 2nd problem is x=4
In the first problem, you need to subtract the 8 from both sides of the equation then divide 4 by both sides which makes 4 cancel itself out leaving x and 12 leaving 1.

A rectangular garden covers 16,000 ft2. Its length is 60 ft longer than its width.
tatiyna
The width is x 
<span>The length is x+60 </span>

<span>so x(x+60) = 16000 
</span>
<span>x^2 + 60x = 16000 
</span>
<span> </span>
<span>x^2 + 60x + 900 = 900+16000 
</span>
<span>(x+30)^2 = 16900
 </span><span> </span>
<span>x+30 = 130
 </span>
<span>x = 100

So your answer is 100. </span>

Which part of an ecuation is the sum
erastova [34]
All parts of arithmetic equations have names. In an addition equation, addends are the numbers that are added together to give a sum. In a subtraction equation, the subtrahend is taken away from the minuend to give a difference. In a multiplication equation, factors are multiplied to give a product.

Find value of x In x^2+2x
lara [203]

Answer:

See explanation

Step-by-step explanation:

Assuming we want to solve for x in:

{x}^{2}  + 2x = 0

Then we factor to get:

x(x + 2) = 0

Apply the zero product principle to get:

x = 0 \: or \: x + 2 = 0

x = 0 \: or \: x =  - 2

The question is not all that clear, so I assume you are solving for x in the completed quadratic equation.
