áreaBCDE = 128 cm² => BC = 8√2 cm
BC = AB√2 =>
8√2 = AB√2 =>
AB = 8 cm
That question is simple;
314+10 = 324
the answer would be 324
Answer:
-13
Step-by-step explanation:
let the unknown number be x
2x + 4=-22
2x=-22-4
2x=-26
divide both sides by 2
x=-13
Because scientific notation has to be in between 1 and 10, you would need this to be 5.2. Count the spaces and since its getting smaller your exponent is negative.
Your answer should be 5.2*10^(-3)
Your answers are -10 and 4
-10+4=-6
