Question 1 is C and question 2 is A
Answer:
11. -8-4(3+5p) = -180
or, -8-4×3-4× 5p= -180
or, -8-12+20p=-180
or -8-12+180= -20p
or, 160= -20p
or,p= - 160/20
:. p= 8
Step-by-step explanation:
we can multiply small brackets then we can do add and subtract then we can get the value of p
Suppose the sides of the big triangle are called m, x and 12+4=16. We have that the big triangle and the small triangle to the right of the shape (sides x,y,12) are similar. We can take then the ratios of correponding sides and know that they will be equal. Thus, we have that 4/y=y/12. Hence, y*y=48. Thus y=

Answer:
2^7
Step-by-step explanation:
Dividing fractions with exponents means you subtract, so 2^6/2^4 = 2^6-4 =2^2
Multiplying numbers with exponents means adding the exponents, so 2^2+2^5 = 2^2+5 = 2^7
