Remember
a(b+c)=ab+ac
and you can do ANYTTHING to be
L=5B
divide both sides by 5
L/5=B
sub L/5 for B in other equation
L+7=3((L/5)+7)
distribute
L+7=(3L)/5+21
minus 7 both sides
L=(3L)/5+14
time boths sides by 5
5L=3L+70
minus 3L both sides
2L=70
divide 2
L=35
Answer:
340
Step-by-step explanation:
-10[5 - ( 30 + 
× 3) ÷ 2]
Calculate 4 to the power of 2 and get 16.
-10 
Multiply 16 and 3 to get 48.
Add 30 and 48 to get 78.
-10 
Divide 78 by 2 to get 39.
-10 ( 5 - 39)
Subtract 39 from 5 to get −34.
-10 (-34)
Multiply −10 and −34 to get 340
340

<h3><u>Given</u> :</h3>
- 2x²y - 4xy², x = - 1 & y = 1
<h3><u>To Find</u><u> </u> :</h3>
<h3><u>Solution</u> :</h3>
2x²y - 4xy²
<u>Substituting the value of x & y</u>,
= 2(- 1)² × 1 - 4(- 1) × 1²
= 2 × 1 × 1 + 4 × 1
= 2 + 4
= 6
<u>Hence, The value of the expression is 6</u>.
Answer:
11
Step-by-step explanation:
3(2) - (3(3) + 2) + 16
6 - (9 + 2) + 16
6 - 11 + 16
