Answer:
45
Step-by-step explanation:
63/7 is 9
72/8 is 9
5x9 is 45
Answer: 15
Step-by-step explanation:
Area of a triangle = base * height.
Since the inside figure is a square, the base of the triangle must be 5.
To find the height: The length of the entire figure is 17; subtract 5 to account for the square, and you know that the remaining 12 must be divided easily on the right and left side; this shows that the height of the triangle on the left must be 6.
Plug these numbers into the formula: 5 * 6 / 2 = 15 :)
A circle is 360 degrees. When you have 7/10, you would multiply it by 36. This is because in the denominator, 10x36=360. 7x36? 252.
So it would be 252 degrees.
X^2+x-20
x^2+5x-4x-20
x(x+5)-4(x+5)
(x-4)(x+5)
Answer:
B and C are functions but A and D are not
Step-by-step explanation:
Vertical line testing. You draw a vertical line. If the vertical lines passes through one line, its a function. It it passes through more than one line, its not. Or in other words, each input (x-value) has its own output (y-value)
