Answer:
100yd²
Step-by-step explanation:
length=4x
width=x
perimeter=2(l+w)
50=2(4x+x)
50=2(5x)=10x
50=10x
x=5yd
width=5yd
length=20yd
area=length×width
=20×5
=100yd²
Answer:
You can fator it , but you can't solve it
Step-by-step explanation:
Factor 6x+9
6x+9
=3(2x+3)
Answer:
3(2x+3)
Step-by-step explanation:
if 39 passengers in 13 cars then 39 multiplied by 2 = 78 so 13 by 2 = 26 so the cars will be 26
The value of the expression (-4x - 4) + (-4x - 10) is -8x - 14
<h3>What are expressions?</h3>
Expressions are mathematical statements that are represented by variables, coefficients and operators
<h3>How to determine the value of the expression?</h3>
The expression is given as
The sum of (-4x - 4) and (-4x - 10)
This can be represented as
(-4x - 4) + (-4x - 10)
Remove the bracket
So, we have
(-4x - 4) + (-4x - 10) = -4x - 4 - 4x - 10
Collect the like terms
So, we have
(-4x - 4) + (-4x - 10) = -4x - 4x - 4 - 10
Evaluate the like terms
So, we have
(-4x - 4) + (-4x - 10) = -8x - 14
Hence, the value of the expression (-4x - 4) + (-4x - 10) is -8x - 14
