Answer:</h3>
<u>If a rectangle and a triangle have the same area</u>.
Then,
- <u>L × B = 1/2 × B × H</u>
- 10 × 3 = 1/2 × 6 × H
- 30 = 3 × H
- 30/3 = H
- 10 = H
<u>Hence, the height of triangle is 10cm</u>.
Answer:
4. 0 + 1 = 1
Step-by-step explanation:
since 2/9 is a bit small
and
since 10/11 is almost whole
Answer:
f(-4) = -9
Step-by-step explanation:
f(x)=2x-1
Let x = -4
f(-4)=2*-4-1
= -8 -1
= -9
