Answer 1

Ответ:

Пошаговое объяснение:

24ab + 32а - 3b - 4 при а = 0,35 и b =-1

8a(3в+4)-3в-4=

=8а(3в+4)-1(3в+4)=

=(8а-1)(3в+4)=

=(8*0,35-1)(3*(-1)+4)=

=(2,8-1)(4-3)=1,8

ИЛИ

​24*0,35*(-1)+32*0,35-3*(-1)-4=

=-8,4+11,2+3-4=

=-9,4+11,2=1,8

Answer 2

1) 12,6

Решение:

(24+32)а-3b-4=56×0,35-3×1-4=19,6-7=12,6

Answer 3

To evaluate the expression $24ab + 32a - 3b - 4$ when $a = 0.35$ and $b = -1$, substitute the values of $a$ and $b$ into the expression and perform the calculations step by step:

1. Substitute $a = 0.35$ and $b = -1$ into the expression: $24 \times 0.35 \times (-1) + 32 \times 0.35 - 3 \times (-1) - 4$

2. Perform the multiplications and additions: $-8.4 + 11.2 + 3 + 4$

3. Add the numbers: $-8.4 + 11.2 + 3 + 4 = 10.8$

So, when $a = 0.35$ and $b = -1$, the expression $24ab + 32a - 3b - 4$ evaluates to $10.8$.
