To find the answer you will find the area of the parallelogram by multpltig the base (14 in) by the height (10 in).
After this you will divide the answer of 140 square inches by 2 because the area each congruent triangle would be half of the total area.
The answer is 70 square inches for each triangle.
Answer:
x= -2
Step-by-step explanation:
-2 -1 = -3
-3 + 5 = 2
Complementary pairs = APW and ZPW
Answer:
x = 1, y = 2, z = 1
Step-by-step explanation:
Adding the first 2 equations to each other gives
x + y + z + 4x - y - z = 4 + 1
which simplifies to
5x = 5, so x = 1
x + z = 2 so 1 + z = 2, so z = 1 too
x + y + z = 4 = 1 + y + 1 = 2 + y so y = 2
The binomial can be factored using the Difference of Squares;
a^2 - b^2 = (a + b)(a - b) where a = x and b = 10
(x + 10)(x - 10)
<u>Answer: C. x = 10, -10</u>
