Problem Ben is 4 times as old as Ishaan and is also 6 years older than Ishaan.

1 answer:

8 0

B=4i and b=i+6, since b=b we can say:

4i=i+6 subtract i from both sides

3i=6 divide both sides by 3

i=2, and since b=4i

b=8

So Ben is 8 and Ishaan is 2.

I need to know the answer please…

Answer is a= 51/7 or 7 2/7

Step by step

-2/3 (a + 3) = 5/3a - 19

Distribute to resolve parentheses

-2/3a -2 = 5/3a - 19

Now to move variables to one side
Add 2/3a to both sides

-2/3a + 2/3a -2 = 5/3a + 2/3a -19

Combine like terms

-2 = 7/3a -19

Add 19 to both sides to isolate variable

-2 +19 = 7/3a -19 + 19

17 = 7/3a

Divide both sides by 7/3 to solve for a
(Remember when you divide a fraction, flip it and multiply.)

17 * 3/7 = a

51/7 = a

Solve this equation<br>-2(4-7)+5(4+7)

gayaneshka [121]

You can simplify this expression with PEMDAS (parentheses, exponents, multiplication/division, addition/subtraction)

Start with the expressions in the parentheses:

4-7=-3

4+7=11

The expression now reads -2(-3)+5(11). Now, simplify the multiplication expressions:

-2*-3=6

5*11=55

The expression is 6+55 which is 61.

Hope this helps!!

Answer:

-5 + 12 i

Step-by-step explanation:

(2 + 3i)^2 = 4 + 6i + 6i + 9i^2

= 4 + 12 i + 9(-1)

= - 5 + 12 i
