Answer:
x=0
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
10(x−2)=−20
(10)(x)+(10)(−2)=−20(Distribute)
10x+−20=−20
10x−20=−20
Step 2: Add 20 to both sides.
10x−20+20=−20+20
10x=0
Step 3: Divide both sides by 10.
10x/10 = 0/10
Answer:
13
Step-by-step explanation:
Use PEMDAS
2(3+2x5)÷2
first you would do the parenthesis
2 times 5 is 10
so now you have:
2(3+10)÷2You still have parenthesis so you would add 3+10 because that is inside the parenthesis
2(13)÷3
next you would do 2 times 13 which is 26:
so now you have 26÷2 which is 13
so the answer is 13
Answer:
1) The square ABCD was dilated to form square A'B'C'D' using a scale factor of 1/2
2) The pair of polygons is not similar because their corresponding sides are not proportionals.
Step-by-step explanation:
1) Scale factor: f=?
f=Final dimension / Initial dimension
f=A'B'/AB=B'C'/BC=C'D'/CD=A'D'/AD
f=2/4
Simplifying the fraction dividing the numerator and denominator by 2:
f= (2/2) / (4/2)
f=1/2
2) Let's check the proportion between their corresponding sides:
AM/A'M'=(11 ft)/(9.4 ft)=1.17
HT/H'T'=(11 ft)/(9.4 ft)=1.17
HM/H'M'=(10 ft)/(8.4 ft)=1.19
AT/A'T'=(10 ft)/(8.4 ft)=1.19
AM/A'M'=HT/H'T'=1.17 but different to 1.19=HM/H'M'=AT/A'T'
Then, the pair of polygons is not similar
Answer:
6, 12, 21, 10, then 4
