Answer:
x ∈ (-oo ; 3)
Step-by-step explanation:
4x - 7 < 5
4x < 5 + 7
4x < 12
x < 12 : 4
x < 3
x ∈ (-oo ; 3)
Answer:
53thst is the right. answer
Surface area = 2(6*3) + 2(6*2) + 2*(2*3) = 36+24+12 = 72 cm^2
First factor (x square -36), the answer will be (x+6)(x-6).
Second, cancel the x .
6x/ (x+6)(x-6)
4x/(6)(-6)
4x/-36
Answer:
242 cm
Step-by-step explanation:
1. Find the scale factor
A scale factor (SF) is the ratio of two corresponding lengths in similar figures.
SF = actual distance/scale distance
If the scale width is 3.8 cm,
SF = 418 cm/3.8 cm = 110
2. Calculate the actual depth
110 = actual depth/2.2 cm
Actual depth = 110 × 2.2 cm = 242 cm
