Answer:
x=7 (if your teacher cares it could + or - 7)
Step-by-step explanation:
Okay, since it's a 90 degree triangle you can use the Pythagorean theorem
( a^2 + b^2 = c^2)
Since it's an isosceles triangle the other side is x because it's the same value.
x^2 + x^2= (7
)^2
Add the left side
2x^2= 7^2 + ^2 roots and square roots cancel each other out
So -> 2x^2= 49 x 2 =98
just solve for x.
x^2 = 98/2
x^2= 49
Square root both sides
x= 7

Answer:
C
Step-by-step explanation:
You need to find the individual shapes and add them together. The surface area of the 5 squares is 84.64 each. (84.64*5)=423.2. Then you need to find the 4 triangles on top. Each with a surface area of 46.65. (4*46.65)=186.6 you add your total surface areas (186.6+423.2)=609 estimated.
The answer is 6x^5(y+2x-3yz)
Step-by-step explanation:
logx - log3 = log(x-2)
x = 3(x - 2)
x = .......
