Answer:
The first choice
Step-by-step explanation:
It says that its decreasing so the slope is negative.
It also starts of with 565 so that's the y intercept
Answer:
The correct answer is 70.
Step-by-step explanation:
Since they got the same answer we have the equation:
(a + 3)a + 6 = a + 3(a + 6)
a^2 + 3a + 6 = a + 3a + 18
a^2 + 3a - 3a -a + 6 - 18 = 0
a^2 - a - 12 = 0
(a - 4)(a + 3) = 0
So a = 4 or -3.
As a is given as positive we take a = 4.
The correct numerical value =
(4 + 3)( 4 + 6)
= 70.
Answer:#1 C.30 #2 40
Step-by-step explanation:
3x+15=7x-5
3x+15+5=7x-5+5
3x+20=7x
3x-3x+20=7x-3x
20=4x
20/4=4/4x
5=x so if it is an equilateral all sides are equal so 3(5)+15=30 so the answer should be 30
So the triangle in #2 is an isoceles so two of the angles are equal so the equation is 2(2x-24)+3x+4=180
4x-48+3x+4=180
7x-44=180
7x=224
x=32
2(32)-24
64-24=40
