What does b1 and b2 mean in math?
In respect to this, what is b1 and b2 in a trapezoid?
The two parallel sides of a trapezoid are its bases. If we call the longer side b1 and the shorter side b2, then the base of the parallelogram is b1 + b2.
Subsequently, question is, what is a 1 2h b1 b2? A = 1/2h(b1+b2) Multiply both sides by 2. 2A = h(b1+b2) Multiply both sides by 1/h. 2A/h = b1+b2.
Also Know, what does b2 mean in math?
Definition: The sum of two vectors A = (A1, A2, , An) and B = (B1, B2, , Bn) is defined as. A + B = (A1 + B1, A2 + B2, , An + Bn) Note: Addition of vectors is only defined if both vectors have the same dimension. Example: (2, -3) + (0, 1) = (2+0, -3+1) = (2, -2).
What is a formula for a trapezoid?
A trapezoid is a 4-sided figure with one pair of parallel sides. For example, in the diagram to the right, the bases are parallel. To find the area of a trapezoid, take the sum of its bases, multiply the sum by the height of the trapezoid, and then divide the result by 2, The formula for the area of a trapezoid is: or.
Why is the area of a trapezoid?
The area of this parallelogram is its height (half-height of the trapezoid) times its base (sum of the bases of the trapezoid), so its area is half-height x (base1 + base2). Because the parallelogram is made from exactly the same "stuff" as the trapezoid, that's the area of the trapezoid, too.What is A² B²?
( A²+B²) = (A+B)² - 2AB. And, (A²-B²) = (A-B)² + 2AB.What is a2 b2 formula?
a2 - b2 = (a + b)(a – b ) .What is the formula of a2 b2 c2?
a2 + b2 = (b + 2)2 This formula is used to find integer sides on pythagorean triangles. You can find the sides of the triangles with a hypotenuse c that is 2 bigger than b.What does 2a mean in algebra?
Algebraic Terms 2a means 2 × a ab means a × b a means a × a a means a × a × a means a ÷ b means a × a × b ÷ c Adding a. Page 1. A Resource for Free-standing Mathematics Units. Algebraic Expressions. © The Nuffield Foundation.Is zero a positive integer?
An integer is a whole number that can be either greater than 0, called positive, or less than 0, called negative. Zero is neither positive nor negative. Two integers that are the same distance from the origin in opposite directions are called opposites.What is the formula for algebraic expression?
If α and β are the two roots of the equation ax2 + bx + c then, α + β = (-b / a) and α × β = (c / a).Solution:

What is AB squared?
Squaring means multiplying an expression times itself: (ab)2 means (ab)(ab). And when you do regroup and rearrange, you see there are two a's and two b's all multiplied together; thus a2b2.What is a2 b2 2ab?
a − b)2 = a2 − 2ab + b2; a2 + b2 = (a − b)2 + 2ab. 3. ( a + b + c)2 = a2 + b2 + c2 + 2(ab + bc + ca)How do you solve 1 2h BB?
