Answer:
Area = 5(x + 4y - 6).
Step-by-step explanation:
The area of the whole figure = area of rectangle + area of the triangle
= 10(2y - 3) + 1/2 * 10 * x
= 20y - 30 + 5x
= 5(x + 4y - 6).
Answer:
∠1 and ∠4
Step-by-step explanation:
Step-by-step explanation:
Pyramid
1/2 * 12 * 15
6 * 15 = 90
90 * 4 = 360cm
Cube
12 * 12 = 144
144 * 4 = 576cm
576 + 360 =
936 cm² of paint
Answer:
14089386
Step-by-step explanation:
Answer:
-8y^7 - 5y^6 + 9y^5 + 3y^4 - 4y^3
Step-by-step explanation:
Please be sure to use " ^ " to indicate exponentiation. Then,
your 9y5−4y3−8y7−5y6+3y4 becomes 9y^5 - 4y^3 - 8y^7 - 5y^6 + 3y^4.
We must now write that in descending order by powers of y:
-8y^7 - 5y^6 + 9y^5 + 3y^4 - 4y^3
