Answer:
Area =^r²
Area=22/7×9²
=3.14=81
=254.34
5x2-3x=25
Divide each term by 5:
x^2 - 3/5x = 5
Make a trinomial square of the left side by taking the square of half of the coefficient of x.
The coefficient of x is -3, so the square would be (-3/10)^2
Add that to both sides of the equation.
Now you have:
x^2 - 3/5x + (-3/10)^2 = 5 + (-3/10)^2
Simplify both sides:
x^2 -3/5x +9/100 = 509/100
Factor the trinomial:
(x-3/10)^2 = 509/100
Solve for x, , take the square root of both sides:
x-3/10 = +/-√509 / 100
Simplify the right side:
x-3/10 = +/-√509/10
Add 3/10 to both sides:
X = +/-√509/10 + 3/10 ( this is the exact form)
You can then find the decimal answer if needed.
Answer:
i think its 1 1/12
Step-by-step explanation:
+Well you need to multiply 11.3 times 4.5 per each triangle
Also you need to find the base which is a square
So 5.1 times 5.1 which is technically 5.1 squared. You add from there
EQUATION: 4(11.3 x 4.5) + 5.1 squared
You should get 229.41
