A rectangle, is a quadrilateral with all angles at 90°.
a square is a quadrilateral with all equal sides, and right-angles all around.
now, the rectangle as well as the square, have all right-angles, the only difference is that the square has all equal-length sides, whilst a rectangle can have pairs of sides that vary in length.
A. 6 and b. 12. You take 3.6 and divide it by .6 then multiply by 2 for the second answer
To evaluate this, plug in the number 4 for the variable a and the number 5 for the variable 5.
6a + 3ab
6(4) + 3(4)(5)
To solve this multiply then add.
Multiply from left to right and don't add until everything has been multiplied.
Basically, 6(4) + 3(4)(5) = (6 • 4) + (3 • 4 • 5).
6 • 4 = 24
3 • 4 = 12
12 • 5 = 60
Now we have 24 + 60.
Just add and you have your answer!
24 + 60 = 84
So when a is 4 and b is 5, <span>6a + 3ab is equal to 84.
Hope this helps!</span>
First, factor out the common factor 5.
<span>15y^2-50y+35 =
= 5(3y^2 - 10y + 7)
Now we need to factor the trinomial.
3 can be factored as 3 * 1
7 can be factored as 1 * 7 or (-1) * (-7)
Since the middle term is negative, we need to use -1 and -7 as the factors of 7
= 5(3y - 7)(y - 1)
</span>
A=8 and PQ=28.
the way I solved the problem is attached. hope this helped.
