answer : 11

explanation: a2

$a ^{2} + 3b \div c - 2d \\ {3 }^{2} + 3(8) \div 2 - 2(5) \\ 9 + 24 \div 2 - 10 \\ 9 + 12 - 10 \\ 21 - 10 \\ = 11$

a2+3b÷c−2d
3^2+3(8)÷2−2(5) substitute the values in place of the letters
9+24÷2−10 use the relevant equation and find the value
9+12−10 according to the BODMAS u have to divide first (24÷2=12)
21−10=11

incase u didn't know what BODMAS is

B - brackets

O- order of powers

D-division

M-multiplication

A-addition

S-subraction

hope this helps☆☆☆

Answer:

A. The y-intercept of g(x) is less than the y-intercept of f(x).

Step-by-step explanation:

The x-intercept, or when x = 0, of f(x) is -4, the x-intercept of g(x) is -8, so g(x) are neither greater nor equal to f(x), this marks out C and D. The y-intercept, or when y = 0, is in this case f(x) or g(x). The y-intercept of f(x) is 16, the y-intercept of g(x) is 4, so the y-intercept of g(x) is not equal to the y-intercept of f(x), this marks out B. Now to check A, 4 < 16, so y-intercept of g(x) < y-intercept of f(x), the answer is A
