Answer:
16.2 inch²
Step-by-step explanation:
The attached picture consists of 4 equilateral triangles :
Height of equilateral triangle = 2.7 inches
Base of triangle = 3 inches
Area of triangle = 1/2 * base * height
Area of triangle = 1/2 * 3 * 2.7
Area of triangle = 4.05 inch²
Number of square inches of cardboard needed :
Area of each triangle * number of Equilateral triangles
4 * 4.05 inch²
= 16.2 inch²
It will be 37.854 cubic meters
Answer:
1.8889
Step-by-step explanation:
Remember
(abc)/(def)=(a/d)/(b/e)(c/f)
and
(x^m)/(x^n)=x^(m-n)
and
x^-m=1/(x^m)
group like terms
(28/12)(p^9/p^-6)(q^-5/q^7)=
(7/3)(p^15)(q^-12)=
Answer:
9x
Step-by-step explanation:
because they're like terms add them together
3x + 6x = 3 + 6 =
9x, could i have brainliest if possible thanks!
