Answer:
y=-5
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The diagonals of a rectangle are equal and bisect each other
so
step 1
Find the value of x
substitute the given values
solve for x
Multiply by 2 both sides
step 2
Find the value of y
we have
substitute
substitute the value of x
The range of a relation is the possible output values, the y-values.
<h3>Solution :</h3>
By cross multiply, we get
Therefore, answer is 
Answer:
The entire area of the sailboat is 60cm²
Step-by-step explanation:
You can find the area of this shape by breaking it down into simpler shapes and adding up their individual areas.
In this case, the areas we'll use are the rectangle at the bottom, and the pair of triangles at the top.
Because the two triangles can be put together to form a single triangle, we don't need to measure them independently. We can simply take the total length of their bases, multiply it by their height, and divide by two. This follows the rule that the area of a triangle is equal to the area of the square that contains it divided by two.
(2cm + 3cm) × 6cm
= 5cm × 6cm
= 30cm²
The rectangle's area is of course equal to its width times its height, so we can say:
2.5cm × 12cm
= 30cm²
The total area of the shapes then is 30cm² + 30 cm², giving us a total area of 60cm²
Answer:
The first error in the bill is +8
because when two opposite signs of number are multiplied so the result is always negative.
so,
2 × -4 = -8
instead of 8 their should be -8.
hope this answer helps you dear...take care!
