Answer:
1.4
Step-by-step explanation:
add the MADs together then divide them by two.
W=x
L=2x+17
Double everything since we need to lengths and two widths to find the perimeter
2x+17+2x+17+x+x = 76
Combine like terms
6x+34=76
Solve for x
First step is subtract 34 from both sides
6x=42
Next you divide both sides by 6 in order to get x by itself
X=7
Now you plug in 7 into the x’s in length and width
W=7 cm
L=31 cm
THE WIDTH IS 31 CM
Check:
7+7+31+31 = 76 cm
It equals 76 cm just like the problem said so therefore it is right.
It's either the
identity property (e.g. 1*100=100, 1(4+3x)=4+3x, etc.)
or the
distributive property (e.g. 2(3+7)=2*3+2*7=6+7
When x=10, the product of the expression 4x is 40
Product is defined to be the result of the multiplication. If we multiply the value of the x (which is 10) by 4 the result (called the product) will be equal to 40.
