Answer:
<u>1. 40.97 2. 52.93 3. 32.00 4. 26.00 </u>
Step-by-step explanation:
remember that area =1/2 * b * h so to find base, you can make it the subject of formula i.e
b =area *h/2
or in the caseof h you can do
h= area * b/2
2x+5x+5=180 so x has to be 25
To find the perpendicular line, we need to find the negative inverse slope.
y = -1/2x - 2
This line also passes through the point since both have the y intercept / value of -2.
Hope this helps!
Setup 2 problems
2x - 7 < 15 and 2x - 7 > -15
2x < 22 2x > -8
x < 11 x > -4
Or you can write it -4 < x < 11
By cross-multiplying, we get
15x + 30 = 24
15x = -6
x = -3 / 5
