Answer:
61.74
Step-by-step explanation:
so u start off by solving for ghe semicircles.
the formula I wrote for it was:
1/2(3.14)(3)(3)=14.13
then i multiplied it by 2 because the other semicircle so you get:
28.26
then u find the area of the rectangle and subtract 28.26.
15x6=90
90-28.26=61.74
Multiply the numbers on the major axis which are 2 and -9 to get -18. Subtract from that 3*4 = 12. So -18-12 = -30. That's the determinant.
-15+7=-8
Adding numbers with different signs makes it subtraction and the answer will have the sign of the bigger number
x - y = 14
given the ratio x : y = 5 : 3
then let x = 5x and y = 3x, hence equation can be expressed as
5x + 3x = 56
8x = 56 ( divide both sides by 8 )
x = 7
Hence x = 5 × 7 = 35 and y = 3 × 7 = 21
Thus x - y = 35 - 21 = 14
Answer:
When you use the distributive property, you multiply the two numbers together, just like simplifying any product. You will also see another example where the expression in parentheses is subtraction, rather than addition. You will need to be careful to change the sign of your product.
