Step-by-step explanation:
you put the values in place of the variable names and calculate.
y² + x + y
(-4)² + -3 + -4 = 16 - 3 - 4 = 16 - 7 = 9
Answer:
For me,the answer will be A.
im not sure
correct me if im wrong

Answer:
80 cm
Step-by-step explanation:
The diagonals divide the rhombus into four congruent triangles. The height of each triangle is 18/2 = 9, and the hypotenuse is 41. Using Pythagorean theorem, the width of each triangle is:
c² = a² + b²
41² = 9² + x²
x = 40
Therefore, the longer diagonal is 2×40 = 80.
Answer:
C. 70 cm
Step-by-step explanation:
Split all the shapes, so, the square would be:
4 × 10 = 40
---------------------------------------------------------------------------------------------------------------
Each triangle has an area of 7.5:
7.5 × 4 = 30
---------------------------------------------------------------------------------------------------------------
30 + 40 = 70
