Answer:
(a) 26 units
Step-by-step explanation:
The left-side vertical line extends from y = -3 to y = +3, so is 3-(-3) = 6 units long.
The bottom side horizontal line extends from x = -5 to x = 2, so is 2 -(-5) - 7 units long.
The sum of these two sides is 6 + 7 = 13 units. These two sides make up half of the perimeter, which is the total length of all four sides.
The perimeter is 2 × 13 units = 26 units.
Answer:
50ft^2
Step-by-step explanation:
area of triangle ABC=25ft^2
both triangle have equal area and all together it makes a rectangle ABCD so ,
rect. ABCD=25+25=50FT^2
Answer:
Step-by-step explanation:
Flip the equation:
Subtract 6 from both sides:
Divide both sides by 2:
Answer:
1/2 and 5/10 are equivalent because when you reduce 5/10, you get 1/2. Also, whenever we speak, we always say half of 10 is 5. Finally, the factor of 5 made them have an equal value. Therefore, 5/10 and 1/2 are equivalent.
Hope this helps!
<h3><u>The value of a is equal to 34/12 or 17/6</u></h3>
10 + 3(4 - 6a) = -(6a + 12)
Distributive property.
10 + 12 - 18a = -6a - 12
Combine like terms.
22 - 18a = -6a - 12
Add 18a to both sides.
22 = 12a - 12
Add 12 to both sides.
34 = 12a
Divide both sides by 12.
a = 34/12 = 2.8
