Answer:
Step-by-step explanation:
It is a right triangle, so use the Pythagorean Theorem to solve for x.
x² + 8² = 11²
x² = 11² - 8² = 57
x = √57
Answer:
x + y = 29
5x + 2y = 100
Step-by-step explanation:
Here, we want to set up equations
There are 29 problems, so adding up the number of individual problem types will give 29
x + y = 29 ••••••(i)
Let us work with points now;
x is worth 5 points, y is worth 2 points
Thus, mathematically;
5x + 2y = 100 ••••••••••(ii)
Answer: 48 cm^2
Step-by-step explanation:
find the surface area of the rectangles and squares
3(4)=12
3(3)=9
5(3)=15
find the surface area of the triangle
SA=bh÷2
3(4)=12
12÷2=6
both of the triangles have the same base and height so multiply it by 2
6(2)=12
add all of the surface areas
12+9+15+6+6=48
