Step-by-step explanation:
J=(x+4)²
K=(8-x)
X=5
=J+3k
=(x+4)(x+4)+3(8-x)
=(x²+8x+16+24-3x)
=25+25+40
=90
Alternatively:
J=(5+4)²
J=81
K=8-5
K=3
J+3k
81+3(3)
81+9
90

Answer:
9 cookies per dollar
Step-by-step explanation:
This is a fraction equal to
36 cookies ÷ 4 dollars
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 4
36 cookies ÷ 4
--------------------------
4 dollars ÷ 4
=
9 cookies
---------------
1 dollar
=
9 cookies
-----------------
dollar
= 9 cookies per dollar
Answer:
16
Step-by-step explanation:
If we take the partial image to be 1/2 of a full image, then there are a total of
5 1/2 + 2 + 6 + 2 1/2 = 16
acorn images on the graph. Each image represents 4 acorns, so a total of ...
4 × 16 = 64
acorns are represented on the graph. Since these are ones the squirrels ate, the remaining 80 -64 = 16 acorns were left uneaten.
