X+x²=30
x²+x-30=0
(x+6)(x-5)=0
x=-6 or x=5
Answer:
is it asking how many times u would get then number 5 when u roll or asking how you would expect for the first 5 rolls?
The area of a trapezoid can be computed as:
A=(b1+b2)h/2, where b1 and b2 ar the bases, h is the height.
With the provided numerical values:
50=(3+7)h/2
50=10h/2=5h
Answer: h=10inches
Answer:
A. 4.40 square units
Step-by-step explanation:
The triangle is isosceles with base angles of 70°. The a.pex angle will be ...
180° -2(70°) = 40°
The area of a triangle can be computed from two sides and the angle between them as ...
A = (1/2)ab·sin(γ)
A = (1/2)(3.7)(3.7)sin(40°) ≈ 4.40 . . . square units

then simplify by combining like terms -2xy+3y²+17x²
