You pretty much find the area by adding the areas of the 2 triangles and the rectangle together.
10 for each triangle, and 68 for the rectangle.
The total area of the trapezoid should be 78 unites sq.
Hope this helps!! :)
The correct answer is 110 cm
Explanation:
Fractions always include two values (one at the top and the other at the bottom) and they represent the proportion of something, for example, 1/2 of an apple means there is only half apple. Now, to calculate how much is 5/7 of 154 centimeters, simply divide the total number into the denominator (bottom number) and then multiply the result by the numerator (top number). This process is shown in detail below:
- 5 is the numerator and 7 is the denominator
5/7 of 154 cm
154 cm / 7 = 22
22 x 5 = 110 cm
Answer:
No
Step-by-step explanation:
If A were reversible, then such y coudnt not exist, because A⁻¹y would be a solution of the equation Ax=y. This means that A in not reversible, thus, there exist a non zero vector w in R³ such that A*w = 0. If x' were a solution of Ax =z, then x'' = x'+w is a different solution of the equation: Ax'' = A(x'+w) = Ax'+Aw = z+0 = z. This means that a vector z such that there exist a unique solution for the equation Ax=z cant exist.
Answer:
D
Step-by-step explanation:
If you multiply something that is a negative number by something that is positive, in this case, the power of 2, then the answer will still be negative. So -5 ^ 2 is negative 25. When you calculate the power of a negative number, then the result depends on the power of the number, so if it's a positive 2 then the answer will be positive.
