Answer:
243 cm^2 + 108 cm^2 = 351 cm^2
Step-by-step explanation:
So, we have a rectangle and two triangles, we know all the sides or angles.
Rectangle: with 9 cm lenght 15cm + 12 cm = 27 cm
Formula: A=wl -> A=9*27 = 243 cm^2
Trianlge: A=ab/2
Angle 90°
Side A 12 cm
Side B 18 cm - 9 cm = 9 cm
A=ab/2=12·9/2=54 cm times 2 (for the opposite side) = 108 cm^2 = 351 cm^2
Answer:
x=−7+√130 or x=−7−√130
Step-by-step explanation:
Answer:
2(u-5)-6u
2u-2•5
2u-10
2u-10-6u
2u-6u-10
-4u-19
Step-by-step explanation:
P = 2(L + W)
L = W + 3
these would be ur equations...and u would sub in 26 for P
252 seeds
Since there is 42 seeds in each of the 12 bags you need to multiply 42 and 12
42 × 12 = 504
So in total she has 504 seeds, now you need to split that in half by dividing 504 and 2
504 ÷ 2 = 252
Therefore she has 252 seeds left
Hope this helps! :)
