Answer:
<h2>
x= −5−11√13/2, −5+11√13/2</h2>
Solve the equation for x by finding a, b, and c of the quadratic then applying the quadratic formula.
Exact Form:
x= −5−11√13/2, −5+11√13/2
Decimal Form:
x=17.33053201…,
−22.33053201…
Step-by-step explanation:
x(x+5)=387
Simplify
x(x+5).
x^2+5x=387
Subtract 387 from both sides of the equation.
x^2+5x−387=0
Use the quadratic formula to find the solutions.
−b±√b^2−4(ac)/2a
Substitute the values a=1, b=5, and c= −387 into the quadratic formula and solve for x.−5±√5^2−4⋅(1⋅−387)/2⋅1
Simplify.
x=−5±11√13/2
The final answer is the combination of both solutions.
x=−5−11√13/2, −5+11√13/2
The result can be shown in multiple forms.
Exact Form:
x=−5−11√13/2,−5+11√13/2
Decimal Form:
x=17.33053201…,
−22.33053201…

Answer:
37in.^2
Step-by-step explanation:
So if the triangles at the top have a hypotenuse of 5, and a length of 4, then doing reverse Pythagorean theorem, you find out that the width is 3.. so reverse of that for this problem would be and if we plug it in, we get 25 -16=9 and the square root of 9 is 3. so if we find the are of the triangle, 3*4*1/2=6 and there are 2 triangles so 12 for both triangles. The square is 5*4=20. and the smaller triangles on the side are 1*5*1/2=2.5, and there are 2 traingles so 2.5*2= 5. So 5+20+12=37. You can do this on most calculators, and please put my answer as the brainliest.✌

1.53+25.50=27.03
10%= $2.70
2.70+27.03= 29.73
Answer:
V = 35 unit ²
Step-by-step explanation:
Volume of the prism = Area of the prism base · height of the prism
V = [(5 · 2) /2 ] · 7
V = 35 unit ²
Answer:length =7⅓
Width =14⅔
Step-by-step explanation:
Take length as x
And 2x as width
Perimeter as 44
Formula to get perimeter of a rectangle is 2l+2w
X+x+2x+2x=44
6×=44
X=7⅓
Length =x and x = 7⅓ so width =7⅓ while width =14⅔
