Answer:
See Below
Step-by-step explanation:
Thankfully, all the parts you need are given.
First, find the surface of one triangle
A = 1/2bh
A = 1/2(15)(9)
A = 1/2(135)
A = 67.5
Multiply by 4 to get the sum of all the sides.
67.5(4) = 270
Now find the surface area of one square
A = bh
A = (15)(15)
A = 225
multiply by 5 to get all 5 sides
225(5) = 1125
Add sums together
1125 + 270 = 1395
Answer: (x+5)(x-3)2 = 0
Step-by-step explanation: To write this equation as a polynomial, you must multiply it out.
begin by squaring the binomial, and remember to express this as a trinomial (middle term will be -6x).
Then, to finish the job, multiply that trinomial by the factor x+5. Hope this will help you.
Answer:
x=21
Step-by-step explanation:
since the triangle is isosceles, the two lower angles are equal.
2(2x+3)=90
4x+6=90
4x=84
x=21
