Answer:
the answer is that of equations 1
Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply.
Area = L x H
area = 20 x 15 = 300 square feet
Answer:
BD is 3.75 units
Step-by-step explanation:
Given:
BA = 6 units
CA = 8 units
DC = 5 units
To Find:
BD = ?
Solution:
Triangle Angle Bisector Theorem.
An angle bisector of an angle of a triangle divides the opposite side in two segments that are proportional to the other two sides of the triangle.
I.e Here in Δ BAC,
AD is the Bisector of ∠ A
∴ 
Substituting th above given values in it we get
∴ 
∴ 
Therefore BD is 3.75 units
If we move 7 to one side, we have (y^2 + 4y -3) = 0. From this form, we can apply the quadrati formula to solve for the values of y.
To recall, quadratic formula is [ -b ±√ (b² - 4ac) ]/2a.
For our equation, we have a =1, b = 4, and c = -3. If we plug this in, we have y to have approximate values of -2 - sqrt(7) and -2 + sqrt(7)<span>.</span>
