Answer:
E. 2 1/2
E. 8.5 cm
C. 6 cm
Step-by-step explanation:
4............................
Scale factor = AE/AC = (4+6)/4 = 10/4 = 2.5
<u>Correct option is</u> E. 2 1/2
5............................
DE = ?
- DE = √AD² - AE² = √15² - 10² = √125 = 5√3 ≈ 8.66
- <em>For measure of AD see next question (6)</em>
<u>Close option is</u> E. 8.5 cm
6............................
AB = ?
- AD/AB = 2.5 <em>the scale factor as per question 4</em>
- (AB + 9)/AB = 2.5
- 2.5*AB = AB + 9
- 1.5*AB = 9
- AB = 9/1.5
- AB = 6 cm
<u>Correct option</u> C. 6 cm

<span>In expanded form, one must break apart the number and write the parts as an addition problem. This number includes hundreds, ones, tenths, and hundredths. The number 205.95 would be written as 200 + 5+ .90 +.05</span>
Answer:
x<-3.5 or x<2
Step-by-step explanation:
2x²+3x<14
2x²+3x-14<0
2x²-4x+7x-14<0
2x(x-2)+7(x-2)<0
(2x+7)(x-2)<0
2x+7<0 or x-2<0
2x<-7 or x<2
x<-3.5
