False
4x^2+7x^2+x^2=12x^2 not 11x2
1.5 as a percent is 150%
Hope this helps!
SA=2(LW+LH+WH)
if all are trippled then
SA=2(3L3W+3L3H+3W3H)
SA=2(9LW+9LH+9WH)
SA=2(9)(LW+WH+WH)
SA=9(2(LW+WH+WH))
the SA will be multiplied by 9
150 times 9=1350
new surface area is$1350 <span>cm²</span>

- Coordinates (x, y)
- Solving systems of equations by substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = 5x
20x - 4y = 0
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em> [2nd Equation]: 20x - 4(5x) = 0
- Multiply: 20x - 20x = 0
- Combine like terms: 0 = 0
Here we see 0 does indeed equal 0.
∴ our systems has an infinite amount of solutions.
