Answer:
187 cm²
Step-by-step explanation:
The bottom rectangle area is easy, it is 15*9 = 135 cm².
To find the area of the triangle, you only need the base width and its height (you don't need the hypotenuse). You can then use the formula: area triangle is base times half height.
The base width is 15-7 = 8 cm
The height is 22-9 = 13 cm
So the area of the triangle is 13*8/2 = 52 cm²
Together with the 135 of the rectangle that sums to 52+135 = 187 cm².

Answer:
10
Step-by-step explanation:
Given is an isosceles triangle and so:
3x + 20 = 5x export like terms to the same side of the equation
20 = 5x - 3x
20 = 2x divide both sides by 2
10 = x
Option A is correct.
Cathy needs to collect linear data . She should collect the data of option A-The height of a building for 20 years.
Explanation:
Linear data is that data whose slope is always same. Here lets assume, initially the building had 2 floors. Each year 2 floors are added above the previous floors. So our coordinate will be (0,2) (1,4) (2,6) (3,8) and so on.
So slope =
=
= =
So, here slope is 2 for all coordinates.
Answer: x = 3
Step-by-step explanation:
Step 1: Subtract 9 from both sides.
5x+9−9=24−9
5x=15
Step 2: Divide both sides by 5.
5x/5 = 15/5
Divide 15/5 and get 3
