Answer: Choice D. 15 - (-18)
This results in 15 - (-18) = 15 + 18 = 33.
So from -18 to 15 on a number line is 33 spaces.
We can also say
|-18 - 15| = |-33| = 33
The use of absolute value is to ensure the distance is never negative.
Answer:
1465.1 cm²
Step-by-step explanation:
El espejo en forma de diamante tiene la forma de rombo
Tenga en cuenta que: las diagonales del rombo tienen las mismas medidas de esos lados
Por lo tanto, el área del espejo se calcula como:
1/2 × Diagonal 1 × Diagonal 2
Diagonal 1 = 80.5 cm
Diagonal 2 = 36.4 cm
= 1/2 × 80.5 cm × 36.4 cm
= 2930.2 cm² / 2
= 1465.1 cm²
Por tanto, el área del espejo es 1465.1 cm².
I think second must b the answee
I won't tell you the answer but I'll tell you how to do it
first, find the area of the rectangle (lxw)
Next, find area of the triangle (BxHx.5)
Then, subtract the area of the rectangle to the area of the triangle
