Answer:
144cm²
Step-by-step explanation:
Area of square A Aa = La²
Area of square B Ab= Lb²
If the length of each side of square B is 4cm greater than the length of each side of square A, then;
Lb = La + 4 ... 1
Also if the area of square B is 70cm² greater than the area of square A, then;
Ab = Aa + 70
Since Aa = La² and Ab = Lb²
Lb² = La² + 70 ...2
Substitute 1 into 2;
(La+4)² = La²+70
Expand
La²+8La+16 = La²+80
8La+16 = 80
8La = 80 - 16
8La = 64
La = 64/8
La = 8cm
Since Lb = La + 4
Lb = 8 + 4
Lb = 12cm
Area of square B = Lb²
Area of square B = 12²
Area of square B = 144cm²
Answer: B . Ms. Granahan's dog weighs more
Step-by-step explanation:
1 pound = 16 ounces
11 pounds x 16 ounces = 176 ounces
176 + 8 ounces = 184 ounces

Answer:
y = -1/13x + 1 3/13
Step-by-step explanation:
y = 13x + 2
Perpendicular
y = -1/13x + b
Finding b:
1 = -1/13 * 3 + b
1 = -3/13 + b
1 3/13 = b
y = -1/13x + 1 3/13
