Answer:
0
Step-by-step explanation:
Make and equation and solve for x.
(2x+10)^2 = 4(x-5)^2 Now the easiest thing to do is use the formula for squared binomial, (a+b)^2 = a^2 + 2ab + b^2.
4x^2 + 40x + 100 = 4(x^2 - 10x + 25)
4x^2 + 40x + 100 = 4x^2 - 40x + 100
From hear you can cancel out similar terms
40x + 100 = - 40x + 100
40x = -40x
add 40x to both sides
80x = 0
x = 0
The only solution to this is 0.
Answer:
1). x° + 100° + 120° + 100° = 360°
2). x = 40
Step-by-step explanation:
Formula for the sum of the interior angles of a polygon = 
Where n = number of sides of the polygon
From the picture attached,
For n = 4,
Sum of the interior angles of the given polygon = (4 - 2) × 180°
= 360°
Therefore, equation for the sum of interior angles will be,
x° + 100° + 120° + 100° = 360°
x° + 320° = 360°
x° = 360° - 320°
x° = 40°
Answer:
5c + 3(8 - c) = 36
Step-by-step explanation:
A restaurant freezes a cherry and lime juice mixture to create slashes. Cherry juice costs $5 per quart, and lime juice costs $3 per quart. Each day, the restaurant spends a total of $36 on 8 quarts of juice.
Therefore, if there are c quart of cherry juice, then the number of lime juice is (8 - c) quart as the total number of quarts is 8.
Now, the total cost is $36 and therefore, we can write the equation to find the number of quarts of cherry juice is
5c + 3(8 - c) = 36 (Answer)
Answer:$45
Step-by-step explanation:
First you have to find 25% of 60
Which equals 15
60-15=45
$45
Hope this helped!!:D
