Evaluate 5a+ 4b2 when a = 7 and b = 6​

5a + 4b²

⇛5 * (7) + 4 * (6)²

⇛35 + 4 * (36)

⇛35 + 144

⇛179

179

Step-by-step explanation:

5a+ 4b^2

Use PEMDAS:

P- Parentheses, E- Exponents, M- Multiplication, D- Division, A- Addition, and S- Subtraction

5(7) + 4(6)^2 = 5(7) + 4(36) = 35 + 144 = 179

6^2 = 6 x 6 = 36

5 x 7 = 35

4 x 36 = 144

if this is correct please give me Brainliest.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
