Hello hope your day is well i really need help with this expand question 4(a+5)-2(a-5)
BARSIC [14]

Answer:

2a + 30

Step-by-step explanation:

break it down so it is 4(a+5)

then work out -2(a-5)

so 4 x a then 4 x 5 which gives 4a + 20

then -2 x a then -2 x -5 which gives -2a + 10

then when you have 4a + 20 -2a + 10

do 4a - 2a which is 2a

do 20 + 10 which is 30

so the answer comes to 2a + 30

if anything doesnt seem right just comment and i will correct

hope this helps :)

Solve for the width in the formula for the area of a triangle
zmey [24]

Answer: \frac{2A}{h} = w

Step-by-step explanation:

The formula for area of a triangle is A = wh\frac{1}{2}

Now we have to isolate for w.

First multiply by the 2 which is the reciprocal of 1/2 to cancel it out.

2A = wh\\

Now divide by h to isolate w.

\frac{2A}{h} = w
