Answer:
B 36
Step-by-step explanation:
DC^2=6^2+8^2. AD=9cm DB=6cm
DC^2=36+64
DC^2=100
DC=√100
DC=10cm
AC^2=15^2+8^2
AC^2=225+64
AC^2=289
AC=√289
AC=17
P OF TRIANGLE ADC=10+9+17
=36cm
The correct answer is 1. Hope this helps!!
For number one, i believe it would be 6x + 15Y-12. You just multiply 3 by everything i. the parentheses. I hope this helps :)
I see how you would do it but don't know how to explain it sorry
Answer:
a = 40
Step-by-step explanation:
This is a multi-step equation using the distributive property and rational coefficents (fractions). The first step is to complete the distributive property on both sides of the equation and multiply each term in the expression in parenthesis by the constant on the outside. (3/4 x 2a) - (3/4 x 6) +1/2 = (2/5 x 3a) + (2/5 x 20). When we multiply and simplify, we get 3/2a - 9/2 + 1/2 = 6/5a + 8. Next step is to combine like terms: 3/2a - 8/2 = 6/5a +8. We then need to isolate the variable by using inverse operations: 3/10a = 12, then solve for 'a' by multiplying both sides by the reciprocal (10/3) to get a = 40.
