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
You should buy 576 grams of cereal. I believe this is right because 32g x 18=576. But you might want me to work it different or something.
Answer:
(-22,0)
explanation:
You subtract 10 from 8 and you get -2 and if you subtract 10 from -2 you get -12 so there for you are subtracting by 10 on the x-values so if you do -12 - 10 = -22 making your answer (-22,0).
Hope this helps (. ❛ ᴗ ❛.)
