Excercise 1:
No, this is not simplified fully. The full answer would be <span>−7dk+14d−21k</span>−7, not <span>14d - 9 - 21k - 7dk + 2. So, it is not equivalent.
</span><span>
Excercise 4:
</span><span>7dk (2 - 3 - 1) - 7
</span>
Just multiply 7dk into (2) (-3) and (-1)
you'd get:
<span><span>−<span>14dk</span></span>+</span>−<span>7 after simplifying it fully.

p = parameter
w = width
w+2.75
p = 2w+2(w+2.75) = <span>4w</span>+<span>5.5 = 30
Answer to the last one:
w = 6.125</span>
Answer:
Step-by-step explanation:

A.B = A × B

Dimension of the resultant matrix is (3 × 3)
Answer:
Values that make it equal:
-4, -3, -1, 0, 4
Written equivalent inequality:
h≥−4
Step by Step for the written inequality:
h/4 ≥−1
Multiply both sides by 4. Since 4 is positive, the inequality direction remains the same.
h≥−4
