Answer:
w is 10 and l is 5
Step-by-step explanation:
l=w-5
lw=50
w^2-5w-50=(w-10)(w+5) since the negative solution does not make sense w=10 and therefore l is 5 so the length is 5 while the width is 10
Answer:
43
Step-by-step explanation:
You will have to use the PEMDAS rule here. so Parntheses goes first, then exponents, then mutiplicaton or division, and finally addition or subtraction.
20-7= 13
-2^2 = (-2 * -2) = 4
9/3 = 3
so... 13*3 = 39+4 =43
