Six less than means -6 the product of 3 and a number (3 times b) is four=4
-6+3 times b=4
pemdas
multiplication first
3 times b=3b
3b-6=4
add 6 to both sides
3x=10
divide both sides by 3
x=10/3
Answer:
20 units²
Step-by-step explanation:
The x-intercepts are symmetrically located around the x-coordinate of the vertex, so are at
1.5 ± 5/2 = {-1, 4}
Using one of these we can find the unknown parameter "a" in the parabola's equation (in vertex form) ...
0 = a(4 -1.5)² +12.5
0 = 6.25a +12.5 . . . . . simplify
0 = a +2 . . . . . . . . . . . divide by 6.25
-2 = a
Then the standard-form equation of the parabola is ...
y = -2(x -1.5)² +12.5 = -2(x² -3x +2.25) +12.5
y = -2x² +6x +8
This tells us the y-intercept is 8. Then the relevant triangle has a base of 5 units and a height of 8. Its area is given by the formula ...
A = (1/2)bh = (1/2)(5)(8) = 20 . . . . units²
I think 132 cause it’s alternate angles
Answer:
c
Step-by-step explanation:
its right
Answer:
32
Step-by-step explanation:
So you set up the numbers into ratios
8:18
x:72
Based on this, you know 72/18 is four, so you multiply 8 by four to get your answer. 8*4 = 32
