(a+b)•235+349•a+35•b 134•(a-b)+767•b+490•a456•(c+d)-55•d306•c-(15•d+45•d)a=3b=2c=4d=5​

Answer 1

1. (3+2)*235+349*3+35*2=5*235+349*3+35*2=1175+1047+1117=3339

2. 134*(3-2)+767*2+490*3=134+767*2+490*3=134+1534+1470=3138

3. 456*(4+5)-55*5=456*9-55*5=4104-275=3829

4. 306*4-(15*5+45*5)=306*4-60*5=1224-300=924

Answer 2

1) 3339

Answer 3

To solve the expression (a+b)•235+349•a+35•b - 134•(a-b)+767•b+490•a456•(c+d)-55•d306•c-(15•d+45•d) when a = 3, b = 2, c = 4, and d = 5, you can substitute these values into the expression and then simplify:

(a+b)•235 + 349•a + 35•b - 134•(a-b) + 767•b + 490•a - 456•(c+d) - 55•d + 306•c - (15•d+45•d)

Now, substitute the values a = 3, b = 2, c = 4, and d = 5:

(3+2)•235 + 349•3 + 35•2 - 134•(3-2) + 767•2 + 490•3 - 456•(4+5) - 55•5 + 306•4 - (15•5+45•5)

Simplify each part of the expression:

(5)•235 + 1047 + 70 - 134•1 + 1534 + 1470 - 456•9 - 275 + 1224 - (75 + 225)

Now, continue to simplify:

1175 + 1047 + 70 - 134 + 1534 + 1470 - 4104 - 275 + 1224 - 300

Now, add and subtract to simplify further:

(1175 + 1047 + 70 + 1534 + 1470 + 1224) - (134 + 4104 + 275 + 300)

Now, calculate the sums:

7520 - 4813

Finally, subtract:

7520 - 4813 = 2707

So, when a = 3, b = 2, c = 4, and d = 5, the value of the expression is 2707.
