Answer:
A number cubed plus a 3 times a number squared all multiplied by 2 is equal to 4 times a number.
Step-by-step explanation:
Since we can't say "in parenthesis", we will have to say the expressions in the parenthesis first and then say "all multiplied by 2" to express parenthesis in word form. The rest are pretty straight forward.
Answer:
Bottom left
Step-by-step explanation:
It shows that x is a unpredictable number but also show the value of 3 and 7
Answer:
density =8.87g/cm³
From chart the density shows that it is a Colsibro copper alloy, a precipitation hardening copper nickel silicon.
Step-by-step explanation:
This problem bothers on the density of substances
Given data
Mass m of substance = 239.6grams
length l=3cm
width b=3cm
height h=3cm
Volume of substance =l*b*h
=3*3*3=27cm³
We know that the density of the substance ρ=mass/volume
ρ= 239.6/27= 8.87g/cm³
Answer: B
Step-by-step explanation:
1. Multiplying two negatives equals a positive.
2. Reduce the numbers with the GCF, 3.
3. Reduce the numbers with the greatest common factor, 2.
4. Multiply the fractions which would give you: 5/6
Answer:
PART A :
AREA OF RECTANGLE = LENGTH × BREADTH
A = (4x + 5) (3x + 10)
A = 12(x^2) + 55x + 50
PART B: The above is a trinomial with the second degree. Trinomial because it has 3 terms and second degree because the variable(x) is squared.
PART C : Closure under addition and multiplication. Look at the signs.
