Answer 2

Answer:

1)b.48 2)d.81 3)a.11 4)b.–81 5)–246 c.5ft a.19 9/25 in² d.11 mi/h a.48 C.a=m–c/–b

Step-by-step explanation:

4²+(4×2³)=16+(4×8)=16+32=48

(–3)⁴=3²×3²=9×9=81

–2n²+5n+9 (n=2)

–2(2²)+5(2)+9=–2×4+5×2+9=–8+10+9=11

3x³ (x=–3)

3(–3)³=3×–27=–81

4r²–2s³ (r=1 s=5)

4×1–2×125=4–250=–246

A=½bh. ½b=A/h. b=2A/h

then b=(2×30)÷12=5ft

area of a square=s×s=

$4 \times \frac{2}{5} \times 4 \times \frac{2}{5} = \frac{22}{5} \times \frac{22}{5} = \frac{484}{25} = 19 \times \frac{9}{25} {in}^{2}$

d=rt then r=d/t

then r=15.4÷1.4=11 mi/h

(–h–3j)²/h (h=3, j=–5)

(–3–3×–5)²÷3=(12)²÷3=144÷3=48

m=c–ab m–c=–ab m–c/–b=a
