Select 2 strategies that we can use to add 115+497

Gemiola [76]

Answer:

B. Add 115+500 then subtract 3

C. Add 112+500

Step-by-step explanation:

Any strategy that gives a sum of 612 will work. Strategy A gives a sum of 602, so is not useful.

The appropriate choices are B and C.

B: 115 +497 = 115 +(500 -3) = (115 +500) -3

C: 115 +497 = 115 +497 -3 +3 = (115 -3) +(497 +3) = 112 +500

General Formulas and Concepts:

Calculus

Integration

Integrals
Definite/Indefinite Integrals
Integration Constant C

Integration Rule [Reverse Power Rule]: $\displaystyle \int {x^n} \, dx = \frac{x^{n + 1}}{n + 1} + C$

Integration Property [Multiplied Constant]: $\displaystyle \int {cf(x)} \, dx = c \int {f(x)} \, dx$

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle \int {84} \, dx$

Step 2: Integrate

[Integral] Rewrite [Integration Property - Multiplied Constant]: $\displaystyle \int {84} \, dx = 84\int {} \, dx$
[Integral] Reverse Power Rule: $\displaystyle \int {84} \, dx = 84x + C$
