2x + 3
2x + 3
2x * 2x = 2x^2
2x * 3 = 6x
2x * 3 = 6x
3 * 3 = 9
Add them all up
2x^2 + 12x + 9
x = 37.5 (or)
Solution:
Given .
Let us take BE = x and BC = 25 + x.
To determine the value of x:
If two triangles are similar then the corresponding angles are congruent and the corresponding sides are in proportion.
Do cross multiplication, we get
Subtract 30x from both sides of the equation.
Divide by 20 on both sides of the equation, we get
x = 37.5 (or)
Hence the value of x is 37.5 or .
6c^2-5d+8
6 (5)^2-5(4)+8
30^2-20+8
900-20=8
880-8=872
ANSWER:872
Answer:
$70
Step-by-step explanation:
The graph goes through the points (0, 10) and (8, 22), so the slope is ...
(22 -10)/(8 -0) = 12/8 = 1.5
Then the cost of a 40-pound box will be ...
cost = 1.5×pounds + 10
cost = 1.5×40 +10 = 70
It will cost $70 to airmail a 40-pound box.
