Answer:
31
Step-by-step explanation:
So the answer is 31 because
Carson ran 43
Jayden ran 12 miles less
so subtract 43-12=31
There are infinity answers to this.
But, if we are talking whole numbers, there are none
59 is prime

Answer:
Step-by-step explanation:
We have
square with sides <em>s = 3cm</em>
four triangles with base <em>b = 3cm</em> and height <em>h = 9cm</em>.
The formula of an area of a square:
The formula of an area of a triangle:
Substitute:
The Surface Area:
Answer: if the y-intercept is 5, it's c. -3/4x + 5. Since it's ax+b a = slope b = y intercept
Step-by-step explanation:
Answer:
315 cm²
Step-by-step explanation:
Given the scale factor of 2 similar figures is a : b , then
ratio of areas = a² : b²
Here the scale factor = 7 : 21 = 1 : 3 , thus
ratio of areas = 1² : 3² = 1 : 9
That is the area of the enlargement is 9 times the original, so
area of enlargement = 35 × 9 = 315 cm²
