Answer:
Not factorable.
Step-by-step explanation:
We have a trinomial (3 terms). We factor by splitting the middle term 4t into factors of -7 (the last term) which add to 4.
-7 = 1 * -7
4t= 1t+-7t doesn't work
4t=-1t+7t doesn't work
This is not factorable.
Answer:
<h2>351. 86 yd² </h2>
Step-by-step explanation:
As = 2πrh + 2πr²
where r = 4, h = 10
plugin values into the equation:
As = 2π (4) 10 + 2 π (4)²
As = 251.33 + 100.53
As = 351. 86 yd²
Answer:
77 Sq m
Step-by-step explanation:
Area of the shaded shape = Area of the rectangle with dimensions 14 m by 8m - Area of rectangle with dimensions ( 14 - 5 - 2=7) 7m by 5m.
= 14*8 - 7*5
= 112 - 35
= 77 Sq m
Answer:
y= 3x+5
Step-by-step explanation:
start with the linear equation formula
y= mx+b
indentify what you already have.
x= -1 and y= 2 and m(slope)= 3
We are solving for b, so plug in what you have.
2= 3(-1)+b
Simplify.
2= -3+b
Add 3 on both sides.
5= b
Rewrite your equation with the x and y values.
y= 3x+5
